HYDRAULIC OIL
Using dipstick, measure oil level, and oil if
necessary.
When changing hydraulic oil, clean
suction strainer(screwed into outlet port
pipe) and line filter(screwed into inlet
pipe). Line filter uses paper element, so
replace periodically(every 6 months or
1200 hours)
GROUP 2 OPERATIONAL CHECKS AND TROUBLESHOOTING
1. OPERATIONAL CHECKS
CHECK ITEM
Check visually for deformation, cracks or
damage of rod.
Load maximum load, set mast vertical and
raise 1m from ground. Wait for 10
minutes and measure hydraulic
drift(amount forks move down and amount
mast tilts forward).
·
Hydraulic drift
- Down(Downward movement of forks)
: Within 100mm(3.9in)
- Forward(Extension of tilt cylinder)
: Within 5
。
If the hydraulic drift is more than the
specified value, replace the control valve
or cylinder packing.
Check that clearance between tilt cylinder
bushing and mounting pin is within
standard range.
