3 OPERATION
Follow all the safety procedures in Chapter 1 of this manual and in the manual supplied with your hydraulic power unit.
Failure to do this can cause equipment damage and/or personal injury.
Make sure you are wearing all your safety
equipment including approved NIOSH or MSHA respirators during dry cutting or a wet suit during wet cutting.
3.1
COMPONENT PRE-START CHECKS
The following components must be checked before you can use the saw safely. Running the saw with an undetected
defect in either of these components will quickly cause equipment damage.
1.
Hydraulic system
2.
Flanges and Blade
3.1.1 Hydraulic System
1.
Before making any hydraulic connections, inspect all hoses for leaks and risks of rupture as follows:
a.
Inspect each hose for breaks, cracks, worn spots, bulges, chemical attack, kinks or any other damage. Never
stop any detected leak with your hand or fingers. Do not put your face close to suspected leaks. Hold a piece of
cardboard close to suspected leaks and then inspect the cardboard for signs of hydraulic oil.
b.
Replace a damaged hose immediately. Never repair the hose.
2.
Clean fittings before making connections to prevent contamination of hydraulic system. First connect the return
(tank) line from the saw return port to the hydraulic power source return port. Then connect the pressure line from
the saw pressure port to the hydraulic power source pressure port.
3.
Pressure relief valve must not exceed 2500 psi @ 8 gpm. The pressure relief valve must be located in the supply
circuit between the power supply and tool to limit excessive hydraulic pressure to the tool.
3.1.2 Flanges and Blade
1.
Inspect the flange and arbor flange for gouges, hairline cracks, and wear. Replace these flanges immediately if any
of these conditions are present as described in Chapter 4.
2.
Be sure flanges are clean and straight so blade will run true on sides.
3.
Always use the blade recommended by the blade manufacturer for your application. Use approved dry cutting type
blades in dry cutting operations and approved wet cutting type blades in wet cutting operations.
4.
Inspect the blade for cracks, chips, gouges, or loose or missing tips. Destroy the blade if any of these conditions are
present.
5.
Insure a blade is installed to blade manufacturer’s specified direction of rotation. Saw rotation is clockwise as
viewed from the blade side of the saw.
3.2
STARTING THE SYSTEM
1.
This saw is not insulated. Do not start cutting without first checking for live electrical wiring near the cutting site, or
imbedded in the cutting medium. If power lines are unavoidable, consult power company before starting operation.
