1. Load the maximum weight, and then raise the fork
about 70 cm from the ground.
2. Tilt the mast vertically to level the fork.
(Use the tilt lever.)
3. Draw a straight line over the inner mast and the outer
mast.
4. Measure the drift of lift 10 minutes later.
1. Load the maximum weight, and then raise the fork
about 70 cm from the ground.
2. Tilt the mast vertically to level the fork. (Use the tilt
lever.)
3. Measure the tilt drift of the piston rod of the tilt cylinder
5 minutes later.
7d-3-3. Drift for lift and tilt - inspection
If the drift of the lift is measured at the top
