4.2 SAFETY DEVCIES

4.2.1 Emergency stop switch On the control box there is a red emergency button (Fig. 4-1). Pressing the emergency button will switch off all the functions. Pulling out the emergency button restarts the system after a delay of 2 seconds so that it is possible to restart the diesel engine. The other functions will only be released for operation after 15 seconds, and during this time, the acoustic signal of the overload safety device will again be sounded.

Fig. 4 Control box 1. Emergency stop button 344

4.2.2 Driving alarm, acoustic The scissor lift is equipped with an acoustic driving alarm that will sound repeatedly while driving. 4.2.3 Driving alarm, visual As an option, the scissor lift can also be equipped with a visual driving alarm which will automatically switch on the while driving. 4.2.4 Limit switches Platform height in the transport position (< 4 meters): Hydraulic stabiliser operation is possible; Lifting is only possible if all the hydraulic stabilisers are fully withdrawn or if all the hydraulic stabilisers have adequate ground contact; High driving speeds are possible; The oscillating axle is active. Platform height of 4 meters: Hydraulic stabiliser operation is blocked; Lifting is blocked if the permissible slope is exceeded; High driving speeds are blocked; The oscillating axle is blocked; Driving and steering are blocked when the shaft is oscillating;


21-11-2007 Page 18

Platform height from 8 meters onwards, with the key switch in the “0” position: Lifting is blocked if the scissor lift has not finished hydraulic stabiliser operation; Driving and steering are blocked. Platform height from 8 meters onwards, with the key switch in the “1” position: Lifting is blocked if the permissible slope is exceeded; Driving and steering are blocked when the shaft is oscillating; 4.2.5 Tilt alarm If the maximum tilt is exceeded with a platform height of over 4 meters, a warning signal sounds and all movement functions are disabled with the exception of the lowering function and retraction of the platform. To restart the machine, the platform should be lowered fully and a more level surface should be found (Fig. 5).

Fig. 5 Tilt alarm 346 4.2.6 Overload safety device The scissor lift is fitted with an overload safety device. A warning signal sounds three times and the overload light flashes when 80% of the permissible working load is reached (Fig. 15-12). If the permissible working load is exceeded (between 100-120%), all movement functions on the scissor lift will be disabled. An acoustic signal also sounds continuously and the overload light is illuminated (Fig. 15-12). If the overload safety is triggered, the excess load must be removed, after which the movement functions of the scissor lift can be reactivated. It is advisable to take some means of communication onto the platform in case of a fault. 4.2.7 Safety device for lift cylinder A limit switch prevents internal mechanical stopper in the lifting cylinder just before the maximum stroke length is reached (Fig. 6-1). Fig. 6 Safety device for lift cylinder 1.Limit switch 81


21-11-2007 Page 19

4.2.8 Emergency lowering device In the event of an emergency, the platform can be lowered by opening an emergency lowering valve on the lift cylinder. This is activated by pulling out the knob on the valve. Fig. 7 Emergency lowering device 82

Fig. 8 Hand pump platform on 345

If the platform is still extended, one should act according to Situation 2 (Fig. 8). When the valve box is opened, the handles must be in the Situation 1 (Fig. 8) (resting position). Before emergency lowering, the platform must be withdrawn (emergency lowering is not permissible with the platform in the extended position). By moving with the handles of the pump and the three-way valve as far down as shown in Situation 2 (Fig. 8), the pump can be operated using the pump lever with an upward and downward movement, whereby the platform can be withdrawn. Emergency lowering can be started when the slide-out platform is fully withdrawn. After emergency lowering is completed, the handles should be reset into the resting position as shown in Situation 1. Note! Situation Fig.3 is for releasing the locking brakes (parking brakes), for further instructions, see 5.5.1. 4.2.9 Piping and hose leak safety device The lift cylinder is fitted with an electrically controlled valve. Lowering is only possible with the control signal from the control cabinet,

Fig. 9 Pipe/hose leak safety device 83

even in the case of hose leakage (Fig. 9-1). The maximum lowering speed is limited by a throttle installed in the cylinder.

4.2.12 Platform during transport If during transportation, the platform railings are not folded up, one should ensure that the same are duly mounted (including the locking system) before operation. Never work with the scissor lift unless all the locks are in place. Never remove the railings during use. The platform should be withdrawn during transportation. 4.2.13 Oscillating axle The scissor lift is equipped with a oscillating axle, which makes it possible to continue driving on an uneven surface with four driven wheels. When the oscillating axle is not horizontal and the platform is more than 4 metres high, the oscillating axle is blocked and the driving function is automatically switched-off.

The fault indication lamp on the control box will then flash. 3. Oscillating crossbeam In order to bring the floating cylinder back into the horizontal position, the scissor lift must be moved to a more even base surface, and the platform height must be less than 4 m. 4.2.14 Hydraulic stabiliser cylinders The scissor lift can be set at the exact horizontal using the hydraulic stabiliser cylinders on an uneven base surface. The hydraulic stabiliser cylinders can only be operated if the platform height is less than 4 metres. If the hydraulic stabiliser cylinders are not fully withdrawn, driving is not possible. The signalling lamp, Fig. 15-19 will flash in such case, and one should then operate the switch in Fig. 15-20 only so long (with the selection switch in Fig. 15-21 pointing forward) until the signalling lamp is lighted continuously. A ground contact protection has also been provided. When the signalling lamp, Fig. 15-23 flashes, not all the hydraulic stabilisers are in contact with the ground. The switch in Fig. 15-20 should be operated (with the selection switch Fig. 15-21 pointing backwards) just so long until the signalling lamp is continuously lighted. The intermediate operation of another function (except for various hydraulic stabiliser functions) is not possible.

5.3.2 Main switch The main switch (Fig. 16) switches the voltage to the scissor lift on and off.

Fig. 16 Main switch 91

5.3.3 Auxiliary switch for lifting/lowering The electrical switchbox in the hydraulic compartment has an auxiliary switch for lifting and lowering with an automatic zero position (Fig. 13-6). This switch may only be used for maintenance work when no persons are present on the platform, or if required. 5.3.4 Start-/stop unit There is a facility on the electrical installation to enable the operation of the diesel engine (start & stop, Fig. 13-8). This is only possible if the control box is connected to the platform or to the plug connection on the chassis (emergency button must be pulled out). There is another lamp test button on the right next to the stop button of the diesel engine on the electrical cabinet. This button is for testing the lamps on the electrical cabinet and the control box.


21-11-2007 Blz. 26

5.4 OPERATION 5.4.1 Preparations Check: • correct operation of all functions • correct operation of all safety devices • the scissor lift for visible damage (do not forget the tires) • the hydraulic system for leaks; • the hydraulic oil level, if necessary top up with Shell Tellus T46. • the diesel oil level, and if necessary, top up the same; • the engine oil level, and if necessary top up the same (see the Deutz manual attached); • the operation of the control lamps (using the test button on the electrical cabinet Fig.13-8).

5.4.2 Operation 1 Turn the main switch on (Fig. 16-1) (turn the handle a quarter turn to the right)

WARNING Enter the platform only via the access gate.

2 Hang the control box on the railing at the front of the platform and plug the connector into the

socket on the platform. 3 Pull out the emergency stop button (Fig. 17-1)

on the control panel (turn it clockwise). 4 Keep the start button pressed down for at least 5

seconds. During this period, a green lamp will flash, which will remain continuously lighted as soon as and as long as the engine is running.

5 The scissor lift can now be operated with the control buttons.

Fig. 17 Control cabinet 1. Emergency stop button 344

5.4.3 The use of hydraulic stabilisers This scissor lift is equipped with hydraulic stabilisers for levelling, that can be operated both individually or simultaneously. The following switches are always related to the hydraulic stabiliser function: Fig. 15-20 / -21 / -24 / -25 / -26 / -27 as well as the signalling lamps Fig. 15-19 / -23. Selection switch Fig. 15-21 determines whether the hydraulic stabilisers are extended or retracted.


21-11-2007 Blz. 27

Each hydraulic stabiliser cylinder can now be individually operated with the switches in Fig. 15-24 to 27. In order to simultaneously operate all the hydraulic stabiliser cylinders, operate the selection switch Fig. 15-20 (forward), which is coupled to an extra function together with the ground contact signalling unit. This means that the hydraulic stabilisers close when there is ground contact and the machine will only be lifted when all the hydraulic stabiliser cylinders have ground contact. This can be seen in Fig. 15-23; this shall now be continuously lighted in case of ground contact and flash if there is no ground contact. The operator should at all times himself visually check that all the four hydraulic stabilisers are in contact with the ground. The horizontal position should be checked with a water level on top of the platform. N.B.: The extension and retraction of the hydraulic stabiliser cylinders in rapid action mode can only be done if the lights in Fig. 15-19 / -23 are flashing. 5.4.4 Automatic levelling The scissor lift is fitted with a levelling device. With this, the scissor lift can accurately position itself in the horizontal (± 0,3 º accuracy). This function will go into operation when the switch Fig. 15-20 is operated (backwards). The switch should be operated just as long as the signalling lamp Fig. 15-22 is continuously lighted. If the switch is prematurely released, the automatic levelling will stop. 5.4.5 Retraction of hydraulic stabilisers - The selection switch Fig. 15-21 should be switched forward (retraction of hydraulic

stabilisers) - The selection switch in Fig. 15-20 should be pushed forward so that the machine

gradually sinks in the horizontal position. - If the machine has a quick-action hydraulic stabiliser cylinder (a hydraulic stabiliser

cylinder that retracts faster than the other three), correction should be done with individual operation (Fig. 15-21 / -24 / -25 / -26 / -27).

WARNING!

If the rapid action of the hydraulic stabiliser cylinders is not corrected, an acceleration of more than 2,5 m/s² may take place.

5.4.6 After use 1 Lower the platform to its lowest position. 2 Press the emergency stop button (Fig. 17-1). 3 Turn the main switch off (Fig. 16-1) (turn the handle a quarter turn to the left). 4 Remove the control box.


21-11-2007 Blz. 28

5.5 TOWING AND TRANSPORT The brakes of the scissor lift are activated whenever the scissor lift is stopped. The brakes must be released to tow the scissor lift. During towing, it is not possible to steer without the engine running. 5.5.1 Releasing the brakes The type M-250DL27-4WD/P/N has gearboxes with integrated multiple disk brakes. For releasing the four multiple disk brakes, the three-way valve (Fig. 13-14) in the valve compartment should be placed as shown in Situation three (Fig. 8-3). The brakes should now be released by building up pressure using the hand pump (Fig. 13-15). The brake can be again gradually (for safety) activated (if stopped with the pumps) with a built-in throttle. The scissor lift can now be towed. The towing speed should never exceed the maximum driving speed (see 2.4). After use, always place the system back in the resting position (Situation 1 Fig. 8-1)

ATTENTION! The scissor lift no longer has any braking function once the brakes have been released as above. The brakes must be reapplied immediately after towing.

N.B. Before releasing the brakes, it is advisable to take precautions to prevent the machine moving. Place blocks or wedges in front of and behind a wheel.


21-11-2007 Blz. 29

5.5.2 Transport When moving the scissor lift with some other means of transport, the following must be taken into account:

• If the gradient is more than 30%, the scissor lift should be moved using a reliable winch. The winch should be fixed on the towing point on the front (Fig. 18-2).

• If the scissor lift is lifted onto the transport vehicle, use the lifting eyes (Fig. 18-1) that are fitted on every corner of the scissor lift.

• HOLLAND LIFT INTERNATIONAL B.V. advises you not to lift the scissor lift without special tools. Contact HOLLAND LIFT INTERNATIONAL B.V.

• The weight of the scissor lift is shown on the manufacturer decal. Take this into account when selecting the means of transport.

• During transport, the chassis must be secured to the means of transport such that no unintentional movement is possible in any direction. Use the lashing eyes (Fig. 18-1).

• The slide-out platform should be retracted. • Always check that the brakes are working properly before loading the scissor lift. • Keep the dimensions of the machine in mind (see 2.4.)

If the railings have been folded down during transport, they must be replaced correctly before using the scissor lift. N.B. Please refer to chapter 3.5.4 in relation to safety during transport.

6.1.2 Lubrication points All lubrication points must be lubricated with Teflon-based grease at least once a month (Art. Code: VETPATROON).

Fig. 20 General view drawing of lubrication points 352

The lubrication points are: • all hinge points on the scissor • on the swivel pins • in the axle between the oscillating axle and the fixed part of the rear axle (both sides); • the pins connecting the scissor and lift cylinder to the chassis (both sides) The slide blocks and contact surfaces of the chassis, platform, hydraulic stabiliser cylinders and the slide-out platform should also be lubricated (for example, with a brush). The protective gauze must be removed before lubrication. Make sure that the fence is replaced properly before the machine is used again.


21-11-2007 Blz. 32

6.2 SCHEDULED MAINTENANCE For information about the maintenance of the diesel engine, please refer to the maintenance regulations of the engine manufacturer (Deutz). 6.2.1 Daily • Check the hydraulic system for leaks • Check the engine oil level. • Check that all safety devices are working properly (see 4.1). • Check the overall operation • Check the scissor lift for damage (with particular attention to the hydraulic stabilisers and

tyres) • Check that the stickers are legible and replace the same if necessary.

6.2.2 Weekly • Check the fluid levels of the batteries; top up with distilled water if necessary. This does not

apply to maintenance-free batteries. • Check all hoses, piping, couplings and other components in the hydraulic system for damage • Check the proper operation and adjustment of the limit switches for the height stops . • Check the hydraulic oil level in the tank and top up with the prescribed hydraulic oil as

required. Fill to a maximum of three-quarters of the level indicated on the gauge. ATTENTION!

These checks should be performed with the platform in its lowest position (except for the height stops!

6.2.3 Monthly • All lubrication points should be lubricated according to the lubrication schedule. 20). 6.2.4 Quarterly • Check all the bolts for the correct torque according to the “Torque specifications” table. • Replace the filter element in the hydraulic system. • Check the fuel filter and clean the same if necessary. • Check the locking and attachment of the pins in the scissor mechanism and the lift cylinder. • Check that adjustments verified with a paint pen are unbroken. • Check the proper working and setting of the tilt alarm. • Check the maximum permissible lifting pressure at maximum workload and maximum

driving pressure (the maximum permissible values are shown in the documentation). If the maximum pressures are exceeded, please consult the manufacturer.


21-11-2007 Blz. 33

6.2.5 Annually • Change the hydraulic oil. Only use the specified type of oil. • Change the engine oil (after ± 250 hours of operation). • Have the scissor lift inspected by an expert. 6.2.6 Every five years Check all scissor hinge points for play, wear and tear and damage. The scissor mechanism must be dismantled for this. Check all surfaces of the bearings and pins. If the pin and bearing surfaces have a surface roughness of more than 1,0 µm they must be replaced. This also applies if the chrome layer is worn through. Check the pins for any damage and replace if necessary. The play between the pin and bearing must not exceed the limits in the table. The minimum depth of the bearing grease chamber must be 0,40 mm. If one of these two rejection thresholds is exceeded, the bearing (and pin if necessary) must be replaced. Pins that appear to be stuck or improperly lubricated must be replaced. These checks should be carried out by an expert and must be recorded in the service schedule. If in doubt, contact Holland Lift International B.V.
