3.4. Hydraulic System
The hydraulic system should be drained, flushed and refilled,
and the pressure relief valve setting should be checked and
adjusted. This will maintain proper lubrication properties
within the system.
To drain reservoir, remove reservoir filter assembly.
Siphon oil from reservoir and purge oil out of hydraulic
system. Remove and clean screen in outlet ports on reservoir
and fill reservoir with proper clean oil. Operate raise and
lower function several times to purge air from system. Check
oil level, fill to line. Put rated truck capacity load on forks and
adjust pressure relief valve, if necessary, so that truck will lift
rated load.
3.5. Brakes
The brake release cylinder should have 3/8 in. to 1/2 in. of
travel. The cylinder travel itself in non-adjustable and the only
brake adjustment is the aggressiveness. Three allen head
screws on transmission cover case adjust brake
aggressiveness.
Loosen all three locknuts and turn set screws out
transmission cover until no force is felt pushing against any
set screw. Turn the set screws back in transmission cover
only until spring resistance is felt. Then turn each set screw
an additional 1/4 in. turn and secure in place with locknuts.
Test braking action.
Before siphoning oil from reservoir, make
certain siphon is clean.
