Inspection, Maintenance and Adjustment
2.
Check O-ring for damages and replace if necessary.
Check position of O-ring at surface of hole.
3.
Place the cover on the access hole. Make sure the spring
retaining cup (1, Figure 21) in the lower section of the
cover is lined up with the spring. The filter assembly rod
must be in a vertical position and perpendicular to the base
of the tank. The cover can be rotated to align the rod into a
vertical position.
4.
Tighten mounting bolts to 4.84 kg•m (35 ft lb).
Check for Leaks in Hydraulic System
1.
Perform a daily walk-around inspection to make sure that
the hoses, piping, fittings, cylinders and hydraulic motors
are not showing any signs of leakage. If any is noted,
determine the source of the leak and repair.
Fill Fuel Tank
1.
At end of each work day, fill fuel tank. Add fuel through fuel
fill cap (Figure 22). When working at a temperature of 0°C
(32°F) or higher, use ASTM No. 2-D or its equivalent. At
temperatures below 0°C (32°F) use ASTM No. 1-D or its
equivalent.
2.
Securely tighten cap after fueling.
NOTE:
If breather holes in cap are clogged, a vacuum
may form in the tank preventing proper fuel flow
to engine. Keep holes in fuel cap clean.
