Electric Value Lift Stackers
(Part # 273203 & 273204)
Instruction Manual
ATTENTION: TO INSURE SAFE AND EASY USE OF YOUR WESCO VALUE LIFT
STACKER, READ THESE INSTRUCTIONS ENTIRELY BEFORE USING.
3. SAFETYINSTRUCTIONS
1) Use on a level paved surface.
2) Don’t load over the maximum capacity and make sure load is balanced.
3) To cool the temperature of the power pack motor, stop use for a few minutes after continuous use with
a load. Otherwise, it can cause damage to the power pack.
4) Recharge the battery when it runs low on power. Do not discharge the battery completely.
5) Don’t touch the chain or any other moving parts on the unit.
6) Close the electric control box before use.
4. INSPECTION BEFORE USE
1) Ensure all parts are undamaged and in working condition. Do not use the stacker and contact the local
supplier if any parts are missing or defective.
2) Check the electric control box.
3) Ensure oil level is optimal and no oil leakage is occurring in the hydraulic system.
4) Check battery power level. The battery has been charged before shipment, but due to extended
delivery times, it can become low.
5) Check the performance of lifting and lowering the fork without a load.
6) Make sure there is no oil leakage a load is lifted or lowered.
5. OPERATION
5.1 Lift/Lowering the Platform (Fork)
1) Lock the parking brake.
2) Turn the switch to ON, there is power and the voltage meter shows over 10.5V.
3) Press the LIFT button, the fork will lift up. Release the button, the fork will stop at its present position, it
will not descend.
4) Press the LOWER button, the fork will descend. Release the button, the fork will stop at its current
position, it will not continue to descend.
5) To prolong the service life of the electric pump, it is necessary to release the button when the fork
reaches the top position.
6) The electric pump is provided with a relief valve. When the load is over 120% of the capacity, the fork
will not lift.
7) Do not leave the stacker lifting a load continuously in order to preserve the motor.
8) When moving the stacker, the clearance between the fork and ground should be more than 8 inches
(200mm).
9) In order to maintain the stability of the stacker, it should be moved slowly while transporting a load.
10) To ensure safety, turn the switch to OFF and remove the switch key after operation.

5. OPERATION (CONTINUED)
5.2 How to Use Charger
1) After continuous use, the battery will be low in power. To recharge for use the coulometer must be
green or the voltage meter must show at least 10.4V.
2) When the red light on the coulometer is showing or the voltage meter reads under 10.4V, the lifting
speed will slow down. The battery must be recharged, If not, it will shorten the service life of electric
pump and battery.
3) Before recharging the battery, please carefully read and fully understand the attached instruction
manual of charger.
4) Before plugging the charger into an outlet, make sure local electric power matches the charger. Then
connect the charger to socket in the electric control box, the battery will begin recharging automatically.
6. MAINTENANCE
1) Inspect the each section for loose bolts and nuts monthly.
2) Inspect the each section, wheel, hydraulic system, electric pump for distortion, worn, and abnormal
noise monthly.
3) Inspect performance of lifting and lowering the fork and other device monthly.
4) Inspect the battery surface for clean and dry monthly. Dirty and wetness may cause leakage of
electricity and descent of voltage.
5) Inspect the terminals, inserters, fuse electric component for loose, broken monthly.
6) Change the hydraulic oil after 20 working hours in the beginning. Then, change the oil every 300
working hours. If the stacker is not used frequently, please change the oil every 18 months.
7) Refer to following sheet when change or fill the oil.
Temperature Oil
23°F～113°F(-5°C～+45°C) L-HM68 Hydraulic oil (equivalent to ISO VG68)
5°F～23°F (-15°C~-5°C) L-HM46 Hydraulic oil (equivalent to ISO VG46)
8) When changing the oil, put the piston at the lowest position, then open the electric control box, remove
the bolt on the bottom the valve plate and the bolt connecting motor and valve plate, the pump section
is disassembled.
9) Clean the valve plate and the oil tank, then fill oil to 80% of oil tank content. And inspect the connection
to avoid oil leakage.
10) Replacing Battery Cover
a. Take the 2 screws off the small panel on the top and remove the control panel.
