7.8 Hydraulic Filter Change
The hydraulic filter should be changed every 250 hours. Hydrostatic
components require extremely clean oil in order to have a long serv-
ice life. Use caution when changing the hydraulic filter. Before begin-
ning the procedure, make sure the machine is in a clean working
environment. Take any necessary measures to prevent dirt or debris
from entering the hydraulic system.
To change the hydraulic filter:
1.
Park the machine in a location suitable for performing service
work, lower the lift arms, stop the engine and remove the key.
2.
Allow the machine to cool, then release any residual pressure
in the hydraulic system by following the procedure in section
4.5 of this manual.
3.
Locate the hydraulic filter behind the operator enclosure, under
the left rubber plug (item 2, fig. 7.7-2).
4.
Clean around the filter head, then remove the three bolts secur-
ing the cover and remove it.
5.
Remove the old filter from the housing and replace it with a
new element. Dispose of the used filter according to local man
dates.
6.
Reinstall the cover and rubber plug as found upon disassembly.
Note:
Should a hydraulic hose or fitting need to be removed for
maintenance or service, always inspect for damage prior to re-instal-
lation. If none is found it may be reused; if damaged, replace the
part.
7.9 Accessory Belt
The engine uses a belt to drive accessories like the alternator, water
pump, and cooling fan. Belts typically stretch and wear during their
service life. As a result, the accessory belt on the PT-30 should be
visually inspected daily for tension, condition, and presence prior to
operating your machine.
To check drive belt:
1.
With the engine off and cool, remove the key from the igni-
tion to avoid accidental start.
2.
Raise the hood at the rear of the machine to access the belt.
3.
Visually inspect the belt to make sure it is present, tight on the
pulleys and and in good condition.
