The Blue Label pallet truck is simple to operate. However, before using the truck, you should
review the handle controls and their operation. ALWAYS follow all safety precautions and
warnings while operating the truck. Refer to Fig. 1 for all operating instructions.
Raising the forks
Position the handle control lever in the RAISE position. Actuate the pump by raising and lowering the control
handle. Each pump should raise the forks approximately 10mm.
Maneuvering the Truck
Position the handle control lever in the NEUTRAL position. This disengages the pumping mechanism and
allows the control handle to be raised or lowered without actuating the pump.
Push or pull the control handle to move the truck. All steering is accomplished by rotating the control handle.
Lowering the forks
Slowly shift the handle control lever upward to the LOWER position.
This releases the hydraulic pressure and allows the forks to lower.
Lift Function
Pumping of the handle causes hydraulic oil to be suctioned from the oil reservoir through the pump cylinder and into the lift cylinder. Hydraulic pressure is
maintainded by the cone lowering valve performing as a check valve.
Lower Function
The cone lowering valve is activated by the procedure of pulling the control lever. This result in oil being released from the lift cylinder and being returned
into the oil reservoir.

The Blue Lable truck is designed to provide years of trouble free service and requires very little maintenance. However, a routine inspection
and maintenance program will prevent costly replacement parts and/or downtime. All service should be performed by a qualified service
person, who has an understanding of pallet trucks and their operation.
Monthly Inspection and Maintenance
Visually inspect the truck for bent or damaged structural members. Repair as required.
Inspect all pivot points, wheels and axle for signs of wear. If worn, replace at once.
Inspect the pump for signs of seal leakage. The presence of a small amount of oil around the pump piston and cylinder rod is normal. However, oil following
from around the pump piston or from the top of the cylinder head cap indicates worn seals. Replace the piston or cylinder seals at once.
Check the pump oil level. With the frame in the lowered position, remove the filler plug.
The oil level should be at the bottom of the hole. DO NOT use brake fluid(use recommended hydraulic oil in the chart below). After checking the fluid level,
reinstall the filler plug.
