MAINTENANCE/SERVICE
HYDRAULICS: Hydraulic Reservoir (continued)
Change hydraulic oil every 600 hours or 3 years.
To drain the reservoir:
1. Loosen hydraulic fitting and remove filler plug
as described under "To add hydraulic oil",
previous page.
2. Disconnect the pump supply hose (A) from the
pump.
NOTE: A drain pan with a capacity of 130 litres
(35 U.S. gallons) will be required.
Hydraulic Oil Filter
Change hydraulic oil filter (B) after the first 100
hours operation and every 250 hours thereafter.
To change:
1. Clean around the filter head.
2. Remove the filter and clean the gasket surface
of the filter head.
3. Apply a thin film of clean oil to the gasket on
the new filter.
4. Install new filter. Turn the filter onto the mount
until the gasket contacts the filter head. Tighten
the filter an additional 1/2 to 3/4 turn by hand.
IMPORTANT: Do not use a filter wrench to install
the filter. Over-tightening can damage gasket and
filter.
Hydraulic Relief Pressure
A possible cause of poor cutting performance
and/or excessive heating of hydraulic oil is low
relief pressure. To check relief pressure, install
pressure gauge at tapped elbow (C). Pressure
should be 4000 psi (27.6 MPa) with tractor engine
at operating speed and PTO engaged. If relief
pressure is low, replace relief valve cartridge (D).
ELECTRICAL
Use electrical tape and wire clips as required to
prevent wires from dragging or rubbing.
Keep lights clean and replace burnt bulbs.
To replace light bulbs:
1. Using a phillips screwdriver, remove screws (B)
from fixture, freeing amber cover.
2. Replace bulb, plastic lens, and reinstall screws.
NOTE: Bulb trade #1156.
