10.3 Cutting Wedges

A - Place work firmly into wedge

cutting jig and set to desired angle.

- Start machine

B - Push mitre fence forward to feed

work into blade.

When cut is complete pull mitre fence

back.

11.0 Saw Dust Collection (optional accessory)

If this machine is operated in enclosed spaces it must be connected to a saw dust collection device.

The dust collection device must have a minimum air flow rate of 20 m/sec.

Connection to dust collector with 100 mm/4" diameter flexible suction hose.

14.1 Tool Maintenance

Residue resin built-up on the saw blade(s) should be removed regularly. Immerse blade in a natrium carbonate solution

or in paraffin/kerosene or mineral turpentine for 24 hours. The residue resin is then easily wiped off with a rag.

14.0 Care and Maintenance

Always disconnect from power before servicing. Do not rely on switch alone.

This machine requires very little maintenance

When changing the saw blade apply a light coat of oil to the arbor bolt.

Regularly apply a light coat of oil to the mitre fence guide rod.

13.1 Problems

If saw blade is stalled by waste, or the discharge port of the chip case clogged, switch machine off and let blade come

to a complete standstill before attempting to remove obstruction.

Switch motor off immediately if blade has stalled. A dull blade is most often the cause for what appears to be a loss

of power of the motor.

An extremely dull blade leaves burn marks in the kerf. Replace or resharpen at once.

After a power failure the machine has to be switched on again.

13.0 Safety Rules

As with all power tools there is a certain amount of hazard involved with the

operator and his use of the machine. Using the machine with the respect and

caution demanded as far as safety precautions are concerned will considera-

bly lessen the possibility of personal injury. If, however, normal safety precautions

are overlooked or completely ignored, personal injury to the operator can

develop.

10.

FOR YOUR OWN SAFETY; READ AND UNDERSTAND INSTRUCTION MANUAL BEFORE OPERATING THE

SAW:Learn the saw’s applications as well as the specific hazards peculiar to it.

KEEP GUARDS IN PLACE and in working order.

REMOVE ALL ADJUSTING KEYS AND WRENCHES: Form habit of checking to see that all keys and adjusting

wrenches are removed from tool before switching it “ON”.

ALWAYS USE SAW BLADE GUARD AND RIVING KNIFE for every operation for which they can be used,

including through sawing. Through sawing operations are those when the blade cuts completely through the work

piece as in ripping or cross cutting.

ALWAYS HOLD WORK FIRMLY AGAINST RIPFENCE OR MITRE FENCE.

USE PUSH-STICK if distance between blade and rip fence is less than 120mm/5".

NEVER PERFORM ANY OPERATION “FREE-HAND”.

NEVER REACH BEHIND, OVER OR UNDER THE CUTTING TOOL WITH EITHER HAND FOR ANY REASON.

Keep hands away from saw blade; do not reach into area 120mm left and right of saw blade.

DIRECTION OF FEED: Feed work into saw blade against direction of rotation only.

AVOID KICKBACKS (work thrown back at you) by keeping the rip fence parallel to the blade, keeping riving knife

and guards in place and operating, by not releasing work before it is pushed all the way past the saw blade, and

by not ripping stock that is twisted or warped or does not have a straight edge to guide along the fence.

12.0 Crane Lifting

For crane lifting swing both lifting eyes, attached to table, upwards.
