CAUTION
!
SAFE PARKING. Before working on truck:
1. Park truck on a hard, level, and solid
surface, such as a concrete floor with no
gaps or breaks.
2. Put upright in vertical position and fully
lower the forks or attachment.
3. Put all controls in neutral. Turn key
switch OFF and remove key.
4. Apply the parking brake and block the
wheels.
Tilt Cylinder Drift Check
To check tilt cylinder drift, a rated capacity load is placed
on the forks, lifted up and held to determine if the tilt cyl-
inder rods moves (drifts) in a specified length of time.
It is recommended that a test load, made up of a full-
capacity load equally distributed on a 1220 x 1220 mm
(48 x 48 in) pallet, be used. The material used to make up
the test load must be stacked to provide load stability and
must not extend beyond the pallet. It must be secured on
the pallet. Refer to the truck data plate for capacity rating.
1. Adjust fork width as wide as possible to distribute
the load. Refer to truck nameplate for capacity rating.
CAUTION
!
Test load must be stacked stably, not extend
beyond the pallet, and be secured on the pal-
let. Clamp the load on the load backrest or
fork bar to avoid sliping out from fork.
2. Drive the forks into the load pallet until the test load
and pallet rest against the load backrest. Apply the
parking brake and chock the wheels.
3. Raise the capacity load 2500 mm (98.5 in) off the
ground and tilt the upright vertical. Shut off the truck.
4. Measure and write down the distance between the
cylinder-spacer face and the rod-end yoke.
