Replacing the Hydraulic Fluid
Service Interval
: Every 100 hours.
Contaminants in fluid may damage the hydraulic
components. Flushing the reservoir tank and hoses with
kerosene after repairs are performed on the tank, hydraulic
pump, or valve is recommended. Contact an authorized
service dealer for hydraulic system repairs.
1. Disconnect the suction hose from the bottom of the
reservoir tank. Next to the hydraulic filter (Figure 20).
2. Allow the fluid to drain into a suitable container.
3. Tilt unit down in front to completely drain reservoir.
4. Install the suction hose and secure with clamp.
5. Refill the reservoir with approximately 10 gallons
(38 L) of SAE 10W30 or 15W40 Diesel Engine Oil, API
Service CH-4 or higher.
6. Maintain fluid level 1 inch (2.5 cm) below the top of the
tank, with the cylinder retracted (Figure 9).
NOTE
: Always dispose of used hydraulic fluid and engine
oil at approved recycling centers only.
Lubricate the Rail I-beam
Service Interval
: Lubricate before every use.
The rail I-beam area where the splitting wedge slides should
be lubricated with general purpose grease. Make sure to
lubricate both the front and the back of the beam face.
Lubricate the Wheel Bearings
Service Interval
: Every 500 hours.
1. The wheel bearing grease zerk is accessible behind the
rubber plug of the dust cover (Figure 21).
2. Lubricate the bearings with No. 2 General Purpose
lithium base grease.
3. Connect the grease gun to the grease zerk and pump
several times until grease comes out around the bearing.
4. Replace rubber plug.

Inspecting the Tires
Service Interval
: Every 100 hours.
IMPORTANT
Keep tires properly inflated. Failure to
maintain correct pressure may result in tire failure and loss
of control resulting in serious injury and property damage.
Operating accidents can damage a tire or rim, so inspect tire
condition after an accident.
Check the tire pressure frequently to ensure proper inflation.
If the tires are not inflated to the correct pressure, the tires
will wear prematurely.
Always replace worn or damaged tires with DOT approved
tires.
See (Figure 22) for the location of the tire identification
numbers.

Figure 23 is an example of tire wear caused by under
inflation.
