BLADE SHAFT V-BELT TENSION

(See Fig. 1)
This saw is equipped with high tension banded V-belts. The
belts are properly tensioned at the factory but after a few
hours of operation they will stretch and become loose.
To Tension V-Belts:
•
Turn Engine Start Switch (1I) to the OFF position.
•
Using the wrench, loosen the horizontal clamping bolts
at the front of the machine.
•
Turn the Tensioning Bolt [at the front of machine] CLOCK-
WISE until the V-Belts are tight.
•
Replace V-Belts in complete sets only.
Never tension V-Belts beyond the original
factory tension. Loose V-Belts result in poor saw
performance and short belt life.
12 HYDRAULIC SYSTEM
The hydraulic system on this saw is used to RAISE /
LOWER the Diamond Blade (2E), to propel the saw
FORWARD or REVERSE, and to release the Parking Brake. The
hydraulic system consists of a Hydrostatic Transmission, a DC
Lift Pump with a Flow Control Valve, a Hydraulic Lift Cylinder
and a Brake Caliper.
•
Check Hydrostatic Transmission fluid level periodically.
Maintain oil level with SAE 10W30 API CLASS SE,CC,CD
motor oil. DO NOT OVERFILL! Check oil level when saw
is level.
•
Change Hydrostatic Transmission fluid every 500 hours
of operation. Fill Hydraulic Reservoir with SAE 10W30 API
Class SE,CC,CD motor oil. DO NOT OVERFILL! Check oil
level when saw is level.
• Check the DC Lift Pump fluid level periodically.
Maintain oil level with Dexron III transmission fluid. DO
NOT OVERFILL!
• The lowering rate of the saw can be adjusted us-
ing the Flow Control Valve at the rear of the saw. If
the saw falls too quickly, turn the knob on the Flow
Control Valve CLOCK WISE until an adequate
lowering rate is set.
13 PARKING BRAKE
• The Parking Brake is a spring applied, hydraulic
pressure release, caliper and disc system. In sim-
ple terms, the brake is locked when there is no oil
pressure. It is released when high pressure oil is
applied. High pressure oil is supplied and held by the
electric lift pump and electric valves.
• When the 12 volt DC current is not supplied, the
parking brake will lock up.
• If the battery is low or weak, the parking brake and
the lift pump will act erratically and not release. If the
engine is running or the battery has an adequate charge,
this will not occur.
