GENERAL POWER TOOL SAFETY WARNINGS

WARNING READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of
  a cord suitable for outdoor use reduces the risk of electric shock.

• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

PERSONAL SAFETY

• 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 may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
• 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 may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• 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.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

POWER TOOL USE AND CARE

• 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 for which it was designed.
• 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.
• Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

SERVICE

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

MACHINE-SPECIFIC SAFETY WARNINGS

CUT-OFF MACHINE SAFETY WARNINGS

• The guard provided with the tool must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator. Position yourself and bystanders away from the plane of the rotating wheel. The guard helps to protect operator from broken wheel fragments and accidental contact with wheel.
• Use only bonded reinforced or diamond cut- off wheels for your power tool. Just because an accessory can be attached to your power tool, it does not assure safe operation.
• The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart.
• Wheels must be used only for recommended applications. For example: do not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.
• Always use undamaged wheel flanges that are of correct diameter for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage.
• Do not use worn down reinforced wheels from larger power tools. Wheels intended for a larger power tool are not suitable for the higher speed of a smaller tool and may burst.
• The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
• The arbour size of wheels and flanges must properly fit the spindle of the power tool. Wheels and flanges with arbour holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
• Do not use damaged wheels. Before each use, inspect the wheels for chips and cracks. If power tool or wheel is dropped, inspect for damage or install an undamaged wheel. After inspecting and installing the wheel, position yourself and bystanders away from the plane of the rotating wheel and run the power tool at maximum no load speed for one minute. Damaged wheels will normally break apart during this test time.
• Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
• Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.
• Hold power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
• Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.
• Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
• Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
• Do not operate the power tool near flammable materials. Sparks could ignite these materials.
• Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

KICKBACK AND RELATED WARNINGS

• ickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging causes rapid stalling of the rotating wheel which in turn causes the uncontrolled power tool to be forced in the direction opposite of the wheel’s rotation at the point of binding.
• For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break under these conditions. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.
  • Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.
  • Never place your hand near the rotating accessory. Accessory may kickback over your hand.
  • Do not position your body in line with the rotating wheel. Kickback will propel the tool in direction opposite to the wheel’s movement at the point of snagging.
  • Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.
  • Do not attach a saw chain, woodcarving blade, segmented diamond wheel with a peripheral gap greater than 10 mm or toothed
  • w blade. Such blades create frequent kickback and loss of control.
  • Do not “jam” a cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or snagging of the wheel in the cut and the possibility of kickback or wheel breakage.
  • When wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding.
  • Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
  • Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel.
  • Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
    ! DO NOT WORK WITH MATERIALS CONTAINING ASBESTOS (asbestos is considered carcinogenic)
    ! TAKE PROTECTIVE MEASURES WHEN DURING WORK DUST CAN DEVELOP THAT IS HARMFUL TO ONE’S HEALTH, COMBUSTIBLE OR EXPLOSIVE (some dusts are considered carcinogenic); wear a dust mask and work with dust/chip extraction when connectable

USE

GETTING STARTED
HOLD THE TOOL WITH BOTH HANDS WHILE STARTING THE TOOL, SINCE TORQUE FROM THE MOTOR CAN CAUSE THE TOOL TO TWIST.
Start the tool before applying to work and let the tool come to full speed before contacting the workpiece. Lift the tool from the work before releasing the switch. Do not turn the switch on and off while the tool is under load; this will greatly decrease the switch life.

ON/OFF

• To unlock switch and turn tool on: push lever B1 forward to unlock paddle switch B2, then squeeze paddle switch.
• To switch tool off: release pressure on paddle switch. The switch is spring loaded and will return to off-position automatically.

LOCK-ON BUTTON

• The lock-on feature, incorporated into the paddle switch, is a convenience for long operations.
• To lock switch on: after paddle switch has been activated  push lock-on button A at rear of tool completely in and release paddle switch.
• To switch tool off: squeeze and release paddle switch.
• In order to try to avoid recoil (a situation where
  the wheel wants to skip out of the material) it is recommended to make cuts in the same direction as the rotation of the wheel.

DEPTH ADJUSTMENT

• Disconnect plug from power source.
• Loosen depth adjustment lever H.
• The foot is spring loaded and will lower automatically. Tighten lever counter-clockwise at the depth setting desired.
• Check desired depth.

LINE GUIDE

The cutting guide notch will give an approximate line of cut. Make sample cuts in scrap lumber to verify actual line of cut.

HOLDING THE TOOL

• Maintain a firm grip and operate the switch with a decisive action. Never force the tool. Use a light and continuous pressure.
• Make sure material being cut is secured in a vise or fixture before attempting to cut.
• Keep your body positioned to either side of the wheel, but not in line with the wheel. It is important to support the tool properly and to position your body such as to minimize body exposure from possible wheel binding and recoil. Grip the tool firmly while cutting and always be ready and able to manage the cut.
• Avoid jamming, twisting or pinching the wheel with the work piece of otherwise applying excessive side pressure to the wheel.
• After completing a cut and the switch has been released, be aware of the necessary time it takes for the wheel to come to a complete stop. Do not set the tool down until the accessory has come to a complete stop.

CUTTING TILE

• Make sure material being cut is secured in a vise or fixture before attempting to cut.
• Turn the tool on and wait for the wheel to reach full speed. For cuts that extend to the edge of a tile, cut all the way through edge(s) along your cut line.
• Score the tile first along your cut line, making multiple passes to progressively cut through the tile.
• This tool does not use wheels designed for face-grinding. If your cut requires a smooth, finished edge, use an appropriate tile finishing tool to refine the tile edge.

PLUNGE OR INTERIOR CUTS

1. Mark the surface to be cut with the desired cut lines.
2. Loosen the depth adjustment lever so that the spring loaded foot releases and goes to the zero depth setting. Leave the depth adjustment lever loose during this cut.
3. Rest the foot of the tool on the workpiece and align the tool’s wheel with the cut line.
4. While holding the tool firmly, press the paddle switch and allow the tool’s wheel to come up to full speed.
5. Slowly plunge/lower the tool and wheel into the workpiece.
6. Guide the tool forward and complete the cut.
7.  Release the paddle switch and allow the tool to come to a complete stop.
8. Remove the tool from the workpiece.

FLUSH CUTTING

First, consider the desired height of the flush cut. For flooring installation, add up the thickness of your flooring adhesive, the flooring itself, and any underlayments or other material that will add to the thickness of the finished floor.

1. Install the flush cutting wheel on the tool.
2. Adjust the depth of the wheel to the desired depth setting.
3. Turn the tool on its side so that the flush cut foot rests against the flooring.
4. Firmly grip the tool. Turn tool on and allow it to come to full speed before entering workpiece.
5. Complete your cut and remove the tool from the workpiece before turning the tool off.

CUTTING LARGE SHEETS

Support large panels and long boards close to the cut. Be sure to set the depth of the cut so that you cut through the sheet or board only and not the table or work bench. The two-by-fours used to raise and support the work should be positioned so that the broadest sides support the work and rest on the table or bench.

STRAIGHT EDGE GUIDE / RIP CUTS

• The straight edge guide (optional attachment) is used for cuts parallel to the edge of the work, and can be used from either side of the foot plate for cutting on the left or right side of the material.
• Rip cuts are easy to do with a straight edge guide.
• To attach, insert straight edge guide, insert fence through slots in foot to desired width as shown and secure with the set screw.

RIP BOARD GUIDE

• When rip cutting large sheets, the straight edge guide may not allow the desired width of cut. Clamp or nail a straight piece of 25 mm lumber to the sheet as a guide.
• Use the right side of the foot against the board guide.

2×4 CUTTING GUIDE

• The 2×4 cutting guide (optional attachment) can be used to quickly and accurately make cuts in 2×4 lumber.

• Since the depth of cut is less than the thickness of a  2×4, one cut on each side of the wood will be required to complete a cut through the workpiece.

  1. Measure and mark the desired cut line on the piece of wood.

  2. Slide the 2×4 cutting guide over the wood in the designated location of the cut.
     NOTE: When using the standard wheel measure a 25 mm offset to properly align the guide to the offset indicator in the cutting guide. While using the flush cut wheel, line the fence of the tool up with the cut line.

  3. Clamp the cutting guide to the workpiece in the desired location to make the cut.

  4. Firmly hold the tool and use the edge of the guide as a fence and make the first cut.

  5. Flip the work piece over while leaving the cutting guide clamped in place and make a second cut to complete the cut through the 2×4.

MITRE/TRIM CUTTING GUIDE
The mitre/trim cutting guide (optional attachment) and flush cutting wheel is a perfect combination to make mitre, bevel, and straight cuts in baseboard, trim, and molding. Angle indicators also aid in making accurate cuts for other common angles like 15°, 22.5° or 30°.

1. Measure and mark the desired cut line on the piece of wood.
2. Position the mitre/trim cutting guide over the wood in the designated location of the cut.
3. Clamp the cutting guide to the workpiece in the desired location to make the cut.
4. Firmly hold the tool and make the cut.
   For straight cuts use the outside edge of the cutting guide as the fence
   For 45° mitre cuts use the angled edge of the cutting guide as the fence
   ! ENSURE THE TOOL IS PROPERLY SEATED IN THE GUIDE BEFORE STARTING THE TOOL AND USE CAUTION WHEN STOPPING THE TOOL WITHIN THE CUTTING RAIL TO ENSURE THAT THE CUTTING WHEEL DOES NOT COME INTO CONTACT WITH THE CUTTING GUIDE.

Mitre cuts (15°, 22.5° or 30°)
Pivot the cutting guide at the designated corner to the desired angle using the angle indicator marking on the cutting guide, complete the cut using the outside edge of the cutting guide as the fence.

45° Bevel cuts

• While using the flush cutting wheel only, place the saw in the cutting rail to complete the cut.
• The guide positions the saw to make bevel cuts in workpieces up to 14 mm thick. To make a cut, first position the tool into the rail so the back of the tool’s foot fits into the keying feature. Switch on the tool and proceed to make the cut. Stop the tool before removing from guide. Determine if an inside left cut (A), outside left cut (B), inside right cut (C), or outside right cut (D) is required and orient the workpiece.

MAINTENANCE AND CLEANING

• NO USER SERVICEABLE PARTS INSIDE. PREVENTIVE MAINTENANCE PERFORMED BY UNAUTHORIZED PERSONNEL MAY RESULT IN INCORRECT CONNECTION OF INTERNAL WIRING AND COMPONENTS WHICH COULD CAUSE SERIOUS HAZARD.
