CABLE SAFETY RULES

WORK AREA
1. Keep the work area clean and well lit. Cluttered and dark areas
invite accidents.
2. Do not operate power tools in
explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools
create sparks which can ignite the dust or fumes.
3. Keep children and bystanders
away while operating a power tool. Distractions can cause you
to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. do not modify the plug in any way. Do not use adapter plugs with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce the risk of electric shock.
2. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
3. Do not abuse the cable. do not
use the cable for carrying, pulling or unplugging the power tool. Keep the cable away from heat, oil, sharp edges or moving parts.
Damaged or entangled cables increase the risk of electric shock.
4. When operating a power tool
outdoors, use an extension cable suitable for outdoor use. Use of a
cable suitable for outdoor use reduces the risk of electric shock.
5. If operating the power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools can result in personal injury.
2. Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
3. Avoid accidental starting. make sure the switch is in the off position before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.
4. Remove any adjusting key or
wrench before turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool can result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

GENERAL SAFETY RULES

6. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
7. A laser beam can cause serious eye injury. do not look into the laser outlet.
POWER TOOL USE AND CARE
1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate which it was designed.
2. Do not use the power tool if the
switch does not turn it on and off.
Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
3. Disconnect the plug from the
power source before making any adjustments, changing accessories, or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool accidentally.
4. Store idle tools out of the reach of
children and do not let persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
5. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts
and any other condition that can affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Tools with sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool and
accessories in accordance with these instructions and in the manner intended, taking into account the working conditions and the work to be performed.
Use of the power tool for operations different from intended use could result in a hazardous situation.

ADDITIONAL SAFETY RULES FOR MITRE SAWS

Page 14

MITRE / BEVEL CUTS

As the number of sides the workpiece has changes, so do the mitre and bevel angles. The chart below gives the cutting angles for a variety of shapes, assuming that all sides are of equal length.
No. of sides Angle mitre or bevel
4 45° 5 36° 6 30° 8 22.5°
10 18°

COMPOUND MITRE CUTS

A compound mitre is a cut made using a mitre angle and a bevel angle at the same time. This is the type of cut used to make frames or boxes with bevelled sides.
1. Set your saw to the required angles and make some trial cuts.
2. Practice fitting the cut pieces together.
• Always try cuts on some scrap
pieces of wood first.

GROOVE CUTTING

Your saw is has a groove plate and thumbscrew that lets you cut grooves.
1. Subtract the depth of the groove from the thickness of your workpiece
• This will tell you the height
above the table surface at which the saw blade must be set (the saw blade height).
14
Page 15
2. Swing the groove plate to the side.
3. Loosen the locking ring (2) and screw out the depth rod (1).
4. Lower the saw head so that the bottom of the blade is at the height required.
• Ideally, put a piece of wood,
the same thickness as the saw blade height below the blade.
5. Adjust the depth rod (1) so that it just touches the groove plate (3), then tighten the locking ring (2).
• The width of the groove will be the width of the saw blade. However, by
moving the workpiece along in small increments, it is possible to cut grooves to any width.
6. Before reverting to normal cutting, remember to return the groove plate to its normal position.

TRANSPORTING THE SAW

1. Lower the head and lock it down using the head lock pin.
