OPERATION CHECKS (every four months)

Raise and lower the Speed-Lift platform with both control handles, checking for smooth platform movement between ground level and maximum lifting height. Speed of the platform up should be approximately 7 seconds to 50” trailer height and the same down again for SL-5000 through SL-16000 models, and 14 seconds for larger units.

Raise the platform above the reservoir channel of the frame and examine the automatic opening of the truck bridge. Lower the platform, checking the bridge as it folds up vertically for smooth folding. Examine the adjustable height bridge wheels for damage or excessive wear.

Check for proper operation and adjustment of the Energy Conservation System (ECS), which permits the motor to run only when the platform is being raised. When properly adjusted, the ECS switch should turn on the motor with the first small movement of the control handle to raise the platform, and shut the motor off when the handle is released.

There is a super cold weather ECS Bypass Switch located on the electric control box which permits the motor to run continuously when in the “ON” position. This should be used only when loading or unloading during below zero weather and if platform travel speeds when lowering seem sluggish. Run the motor in this continuous “ON” position only in cold weather when the lift is actually being used, and normally conserve electric power during the warmer months with it switched in the “OFF’ or Energy Conservation System (ECS) normal use mode. The motor should run only when the platform is being raised with the Energy Conservation System in operation to save electric power.
