ELECTRICAL CONNECTIONS

Caution• NEVER use a power source while it is still connected to another circuit (e.g car battery). Disconnect it before using for the pump

• The available power source must have the same voltage as the pump voltage (either 12 volt or 24 volt DC, depending on model)

• Battery Cable (26) is supplied with 15 Amp Fuse. It can be replaced when needed but only with a fuse of same amperage

1. Aftermakingtheelectricalconnections,switchONthepumpmotorusingRockerSwitch(25)locatedonthesideofpumpbase.

PUMP OPERATION

Caution• The suction height (from the pump to the lowest fuel level) should not be greater than 1 metre

• The tank must be vented or the pump may not prime, or it may lose its prime due to a vacuum in the tank

• A filter should be intalled at the suction line to ensure a clean supply of fluid to the pump

• Do not run pump for more than 5 minutes with nozzle closed. Do not run pump for more than 30 minutes continuously in 1 hour

• Do not use a Curb Pump Auto Nozzle with this pump. Use of a Curb Pump Auto Nozzle may cause priming problems, reduced

output flow, and motor overheating

MAINTENANCE & REPAIR (Refer to EXPLODED VIEW - Page 6)

General Precautions• Switch off the pump motor and disconnect Battery Cable (26) from the power supply before carrying out any maintenance

• Before dismantling the pump, remove it from drum & disconnect it from all the accessories (hose / tube / nozzle holder etc.)

• If the pump has been operated with Fuel Control Nozzle (28) closed, press trigger on the nozzle to release any built up pressure

inside the hose or pump

• Be careful when fitting O-rings and seals. Replace them with new ones when they are removed from the pump. Always lubricate

them with oil or grease before fitting. They must never be threaded over sharp edges when being fitted

Recommended Tools

Combination Wrench

Size 8 mm, Size 24 mmSlotted Screwdriver

• CORRECT ORIENTATION OF VANES as shown in the

images here.

• SMOOTH MOVEMENT OF BYPASS VALVE against the

force of Valve Spring. Do not overtighten Hex Plug (9).

• Ensure all mating surfaces are clean before

reassembly. Apply minor grease on all O-Rings & Seals

before reassembly.

• Always Loosen /

Tighten the bolts in

an even & diagonal

pattern. First

tighten all the bolts

by hand & finally

tighten each bolt by

1 FULL turn using a

tool of correct size.
