Check for cracks at mast stay, tilt cylinder bracket, guide bar, fork carriage and roller shaft weld.
Check visually or use crack detection method. Repair any abnormality.
Set mast vertical, raise forks about 10
cm
from ground and check front-to-rear clearance and left-to-
right clearance between inner mast and fork carriage, and between outer mast and inner mast.
Use these figures to judge if there is any play at roller or rail.
ÂFront-to-rear clearance : Within 2.0
mm
(0.08
in
)
ÂLeft-to-right clearance : Within 2.5
mm
(0.10

)
Check that there is an oil groove in bushing at mast support.
Set mast vertical, raise forks about 10
cm
from ground, and push center of lift chain with finger to
check for difference in tension.
If there is any difference in tension, adjust chain stopper bolt.
Check visually for abnormalities at thread of chain anchor bolt, and at contact surface between
chain wheel and chain.
Rotate chain wheel by hand and check for any play of bearing.
