Use and Care Manual

3. Position work stop if needed.
4. Position blade guides as close to workpiece as
possible.
5. Move speed setting lever to desired position.
Do not move speed setting lever during a
cutting operation.
6. Set a suitable feed rate for that operation on
the hydraulic cylinder dial.
7. Toggle ON switch to begin blade rotation.
Allow blade to reach full speed before
beginning cut.
8. Turn on coolant flow. Adjust flow valves as
needed.
9. Open valve on hydraulic cylinder to allow bow
to descend in a gradual and controlled
manner.
10. The machine will shut off at the completion of
the cut. Turn off coolant flow and remove
workpiece.
11. Return bow to raised position for next cut.
11.4 Evaluating cutting efficiency
Is the blade cutting efficiently? The best way to
determine this is to observe the chips formed by
the cut.
If chip formation is powdery, then the feed rate is
much too light, or the blade is dull.
If chips are curled, but colored — that is, either
blue or straw-colored from heat generated during
the cut — then the feed rate is too high.
If chips are slightly curled and are not colored by
heat, the blade is sufficiently sharp and is cutting at
its most efficient rate.
12.0 Maintenance
Before doing maintenance on
the machine, disconnect it from the electrical
supply by pulling out the plug or switching off
the main switch! Failure to comply may cause
serious injury.
Keep all surfaces clean and free of rust, slag,
chips, and coolant build-up.
Clear metal particles with a small paint brush or
parts cleaning brush.
Clean filter screen.
Do not use compressed air, as it may force chips
into the guide bearings and other critical areas of
the saw.
Wipe saw down with a clean, dry cloth, and oil all
unpainted surfaces with light machine oil.
Keep blade guides clean and free of metal
particles.
Check guide bearings frequently to make sure that
they are properly adjusted and turning freely.
Grease the vise lead screw (Figure 30) as needed,
with a general purpose grease.
Figure 30
If the power cord is worn, cut, or damaged in any
way, have it replaced immediately.
Ball bearings on blade guide assemblies and blade
wheels are permanently lubricated and sealed.
They require no further lubrication.
Place a thin coat of oil on the table surface on
which the vise jaw slides.
12.1 Coolant level
Maintain coolant level. Low coolant level can cause
foaming and high blade temperatures. Replace
dirty coolant; dirty or weak coolant can clog the
pump, cause crooked cuts, a low cutting rate
and/or permanent blade damage. To fill the tank,
remove the filter cup and pour coolant into the hole
to about 80% of full capacity. Full capacity is 9
liters (2.5 gal). Follow coolant manufacturer’s
instructions for proper use and disposal.
12.2 Gear box
To change gear box oil:
1. Disconnect machine from power source.
2. Place bow in vertical position.
3. Remove drain plug (A, Figure 31) and drain oil.
(Follow local regulations for disposal of used
oil.)
4. Reinstall drain plug and return bow to
horizontal position.
5. Remove vent plug (B), and fill gear box
through the hole with approximately 0.3L
(10.14 oz.) of 90W oil.
6. Reinstall vent plug (B).
Completely drain and refill gear box after the first
90 days of operation. Thereafter, change every six
months.
