HYDRAULIC SYSTEM
The hydraulic system on this saw is used to RAISE /
LOWER the Diamond Blade (2E) and to propel
the saw FORWARD and REVERSE, Steer the saw LEFT
and RIGHT, run the Cooling Fan, and release the Parking
Brake. The RAISE / LOWER system as a DC Lift Pump
mounted in the side of the hydraulic tank, two (2) lift
cylinders and a lowering valve. The lowering rate of the
saw can be adjusted with the Flow Control Valve which
is at the rear of the machine under the cowling.
The Steer and Fan system is powered from the hydraulic
gear pump mounted on the engine. Flow is directed to
the steer valve and turning CLOCKWISE or COUNTER
CLOCKWISE sends flow to an actuator. Any excess flow
is sent to the hydraulic motor to cool the radiator.
The propel pump is belt driven off the front of the engine
through an electric clutch. A cable control changes the
direction and speed of flow to the single rear drive wheel.
A dump valve and shuttle valve controls the release
pressure for the parking brake.
Excess oil is run through the water / hydraulic cooler to
keep oil temperature low.
Hydraulic Maintenance
• The hydraulic filter is located at the front of the steering
console. It should be changed after the first 50 hours
and then after every 300 hours of operation.
• Check the hydraulic oil level weekly. Maintain with ATF
oil type F. DO NOT OVERFILL, check oil level ONLY
when saw is level. 3" below top of tank.
