HandleDaily Inspections. To be performed each day before first operation.
1. Check for any distortion, stress cracks or breaks in welds,materials and castings.
2. Check hydraulic unit and components for oil leakage.
3. Check the hydraulic system for proper operation by
examining the forks in the raised position.
4. Check for smooth rolling and free rotation of the hand pallettruck wheels.

Operating Instructions
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 andwarnings while operating the truck. Refer to Fig. 1 for all operating instructions.
Raising the forks
1. 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
1. Position the handle control lever in the NEUTRAL position. This disengages the pumping mechanism andallows the control handle to be raised or lowered without actuating the pump.
2. Push or pull the control handle to move the truck. All steering is accomplished by rotating the control handle.

Lift and Lower Function
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 ismaintainded 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.

Routine Maintenance
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
1. Visually inspect the truck for bent or damaged structural members. Repair as required.
2. Inspect all pivot points, wheels and axle for signs of wear. If worn, replace at once.
3. 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.
4. 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.

Valve is out of adjustment.
Valve is out of adjustment. Cone lowering valve is
defective Lift cylinder U-Packing is defective

Shooting
Add fluid and check for leaks.
See Hydraulic Control Valve Adjustment procedure below.

Replace cone lowering valve Replace U-Packing
See Hydraulic Control Vlave Adjustment Procedure below.

Adjusting Hydraulic Control Valves
1. Loosen Lock Nut and turn Push Bolt out (counter-clockwise), raising it to its maximum height.
2. While pulling up on Control Lever (in position C), turn Push Bolt in (clockwise) until Frame begins to lower.
3. If Frame raise while actuating Operating Handle in neutral (B) position, turn Push Bolt in (clockwise) slightly.
4. Tithten Lock Nut while preventing Push Bolt from turning. If adjustment of Hydraulic Control Valve does not provide proper operation, problem may be due tocontaminated fluid. Then flush hydraulic system.
