7.8 Hydraulic Filter Change
The hydraulic filters should be changed every 250 hours. Hydrostatic components
require extremely clean oil in order to have a long service life. Use caution when
changing the hydraulic filters. Before beginning the procedure, make sure the
machine is in a clean working environment. Take any necessary measures to pre-
vent dirt or debris from entering the hydraulic system.
To change the hydraulic filters:
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 4.6 of this manual.
3.
Locate the hydraulic filters in the right rear corner of the engine
compartment (items 2, fig. 7.7-2).
4.
Clean around the filters, then thread them off and remove.
5.
Replace them with new filters. thread on and tighten according to
instructions on filter label or box. Dispose of used filters according to local
mandates.
Note: Should a hydraulic hose or fitting need to be removed for maintenance or
service, always inspect for damage prior to re-installation. 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-100 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 ignition 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.
