INSTRUCTION
INTRODUCTION
The MK-APC/W walk-behind air saw is designed for simple operation and has been proven to be extremely useful and versatile. A 12" to 20" diameter
diamond blade may be mounted on the saw if it is rated and approved for operation at 3,300 RPM. READ, AND CAREFULLY FOLLOW, THE OPERATING
AND SAFETY INSTRUCTIONS OF THIS OPERATING AND SAFETY INSTRUCTION MANUAL BEFORE USING THIS PRODUCT. Since safety regulations can
vary between different countries and states, you must contact proper authorities and follow all appropriate regulations.
IMPORTANT SAFETY INSTRUCTIONS
No person should attempt to operate this saw without first being trained in the operation of industrial cutting tools. These instructions are not intended as a
substitute for training and experience. The operator must observe safeguards that include, but are not limited, to the following:
• DO NOT MODIFY ANY SAW FROM ITS ORIGINAL DESIGN WITHOUT THE WRITTEN PERMISSION OF THE MANUFACTURER. UNAUTHORIZED
MODIFICATIONS CAN LEAD TO SERIOUS INJURY OR DEATH TO YOURSELF OR OTHERS.
• DO NOT use any blade marked for less than 3,300 RPM.
• DO NOT service the saw or change blades without first disconnecting the power.
• DO NOT install a blade before inspecting the blade for damage.
• DO NOT operate saw with a damaged blade. A damaged blade may fly apart and cause serious injury or death.
• DO NOT use a blade that wobbles when mounted on the saw.
• Verify blade is correct for application before use.
• Verify blade rotation matches the direction arrow on blade guard.
• DO NOT apply power to the blade before spinning the blade by hand to check alignment.
• DO NOT operate with any loose nuts or bolts. Check all nuts and bolts for tightness.
• DO NOT operate without appropriate ear, eye, foot, hand and breathing protection..
• DO NOT operate around any loose or foreign objects that may damage system.
• DO NOT operate saw if arbor shaft has excessive end play.
• DO NOT cut material that the blade is not designed for.
• DO NOT operate saw near combustible material or fumes.
• DO NOT force blade through material to be cut. Always ease blade through material.
MK-APC/W WALK-BEHIND AIR SAW OPERATING INSTRUCTIONS
A. BEFORE OPERATING THE SAW
1. Be sure all nuts and bolts are tight.
2. Check the air supply for the correct pressure (90 PSI Min.) and rating (85 CFM Min.)
3. Turn on air supply and check for leaks.
4. Be sure to clean air hose to discharge any dirt, scale or moisture (and do so before each use).
5. Connect the air hose while pouring a small amount of general purpose air tool oil into other hose connector on the handle to flush out any moisture and
lubricate the motor.
6. Ensure the in-line oiler is filled with Pneumatic Ice Free Oil.
B. WHILE OPERATING THE SAW
1. Before contacting the material to be cut, squeeze the trigger and allow the saw to reach full speed.
2. Ease the saw blade into the material being cut.
3. At the end of the cut, lift the saw until the blade is clear of the cut, then release the trigger.
4. Allow the blade to come to a complete stop before setting it down.
5. Check the in-line oiler for oil level after 2-3 hours of operation.
6. When the rear wheel behind the blade needs to be moved so it is not directly behind the blade, roll the saw onto its side and remove the “R" clip. Pull the axle
out and retain in the outboard position using the “R” clip.
C. AFTER OPERATING THE SAW
1. Shut off air supply and bleed air line to relieve pressure.
2. Remove the air line and fit a protective cover to the air inlet.
3. Clean the saw by removing all accumulated dust.
4. Give grease fitting a couple shots of grease after every 40 hours of operation.
D. ASSEMBLY OF WATER TANK KIT
1. Attach the water tank frame to the saw’s chassis by sliding the frame from the front towards the back. A 3" bolt will secure the top back of the frame to the
handle quadrant and two 5/16" bolts will attach the front leg of the frame to the front of the chassis.
2. Mount the plastic water tank to the frame and secure it with 4 “L" clamping brackets supplied. Attach one end of the water feed hose with the control valve to
the bottom of the water tank. The end with the “Y" should be attached to the two 16" clear plastic tubings.
3. Attach one water feed nozzle to each side of the blade guard. Each nozzle should have a 16" clear plastic tubing attached which is rested against the blade. In
this way, the water will be guided directly onto the cutting surface.
