Service Manual

1. Shimming Mast on Truck.
1.1. Shimming the Platform.
1. Disconnect battery and remove battery from truck.
2. Attach a hoist to top of platform and hoist to loosen
lift chains. This will allow removal of lift chain
anchor pins and electrical cable.
3. Thoroughly clean off all outside dirt around mast
roller bearings.
4. With platform hoisted to the top of the inner
channel, determine the number of shims required
by prying the platform to one side and slipping
shims between the bearings and web on column.
Add shims by hand until no more may be added.
5. Divide shims as equally as possible between the
two bearings and install under bearings.
6. Hydraulically lift up inner column to remove the
platform.
7. Lower platform down inner column to expose the
bearings. Remove bearings to install shims behind
bearings.
8. Raise platform up inner column as far as it will go
under normal operation. Check bearing shimming
as platform is raised.
When blocking mast columns to prevent
lowering, always block both sides of the
column. Otherwise, the truck could tip over
on its side.
WARNING
Be extremely careful when working with
solvent. Even a small explosion or fire
could cause injury or death.
WARNING
Compressed air used for cleaning MUST
be reduced to less than 30 p.s.i., and then
only with effective
chip-guarding and
personal protective equipment.
