1. Always read the instructions.
2. Always wear safety glasses.
3. Fit the spigot (CP1/3) into the appropriate
side of the clamp in the front of the two
holes in the clamp body and tighten
securing nut.
4. Position the clamp on the pipe with the
chain around the pipe and tighten using
the tommy bar (end of CP1/6). Ensure the
clamp is perpendicular to the pipe for an
accurate cut.
5. Invert machine and remove oil plug
(8316). Fill the cavity with Cengar Green
Oil and replace plug.
6. Without connecting the air supply, t the
appropriate blade with the teeth upper
most. Ensure BOTH screws are fully
tightened using supplied T key.
7. Mount the machine onto the spigot whilst
pulling back clamp securing pin (8315).
Slide the machine into the groove in the
spigot. Ensure it is correctly located.
8. When mounted correctly the blade should
be under the pipe so that the weight of
the machine applies the cutting force to
the blade.
9. If using a long blade (MJ450) for larger
diameter pipes attach the supplied bow
guide using the xings provided to ensure
a straight cut is achieved.
10. Attach air supply (5-6 bar).
11. Press the trigger to start the machine and
lock trigger in place with the catch. Gently
bring the blade into contact with the
work gradually release the weight of the
machine to allow the cut to take place
without extra force.
12. When the cut is complete release the
catch to stop the machine. Remove air
supply before attempting to remove
machine from spigot (reverse of 5 above).
DO’S & DON’TS
1. ALWAYS use Cengar green oil for best results. Keeping
the saw clean and well oiled will give excellent reliability,
and a long life.
2. ALWAYS use Cengar Bi-Metal Shatterproof blades,
for safety, and best cuttng performance.
3. ALWAYS isolate the air supply when changing blades.
4. ALWAYS wear eye protection when using sawing machines.
5. ALWAYS isolate the machine when not in use.
6. ALWAYS keep others away from the saw blade
to prevent injury or trapping.
7. ALWAYS have machines vibration tested annually to
ensure exposure is kept to the minimum.
1. NEVER t breakable “All-Hard” blades in Cengar saws,
these can shatter causing injury to yourself and others.
2. NEVER operate saw without wearing safety glasses.
3. NEVER operate saw whilst you, or others are near the
saw blade, which can cause serious injury or trapping.
4. NEVER use excessive force, this may increase vibration
above safe levels.
5. NEVER hold the Cengar saw in a vice by the body, this
will distort the bores, rendering the tool inoperative.
6. NEVER screw nameplates to the body, as the screws
may penetrate an airway or bore.
7. NEVER operate the Cengar saw without lubrication.
8. NEVER be tempted to clean internal parts with anything
other than a clean lint free cloth, and M.S. Cleaner, or
Cengar Green oil.
9. NEVER modify Cengar saws or use non Cengar parts,
this will invalidate ATEX approval, and warranty.
