Step 4. Crack (loosen) fittings shown at side.
Start engine and operate at idle speed.
Place LIFT control lever in RAISE posi-
tion until forks are three feet from ground.
Place TILT control lever in FWD position
and check if hydraulic oil flows from
loosened fittings; place TILT control lever
in REAR position and check if hydraulic
oil flows from loosened fittings,
a. If hydraulic oil does not flow from
loosened fittings, replace control valve
b. If hydraulic oil flows from fittings,
proceed to step 5 (tighten fittings
loosened above).
Step 5. Start engine and operate at idle speed.
Place TILT control lever in FWD position
until mast assembly is tilted fully forward.
Turn engine off and operate control levers
several times to relieve hydraulic pressure.
Disconnect and cap hose fitting connected
to rod end of tilt cylinder assembly.
CAUTION
Don't place TILT control lever in REAR position in following
steps. Hydraulic oil will flow out of disconnected hose fitting.
Start engine and operate at idle speed.
Place TILT control lever in FWD position and hold while an assistant checks for hydraulic oil leakage
at tilt cylinder assembly port from which fitting was disconnected.
Repeat the above for other tilt cylinder assembly.
a. Remove tilt cylinder assembly and repair piston assembly (para 3-30b) if hydraulic oil leakage
is observed.
b. If hydraulic oil leakage is not observed, remove and repair control valve (para 3-30a).
