TABLE DES MATIÈRES

**********************************************************************

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 ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
■ Use this product only with batteries and chargers listed in tool/appliance/battery pack/charger correlation supplement 987000-432.

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.
■ Do not wear loose clothing or jewelry. Contain long hair. Loose clothes, jewelry, or long hair can be drawn into air vents.
■ Do not use on a ladder or unstable support. Stable footing on a solid surface enables better control of the power tool in unexpected situations.

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.

GENERAL POWER TOOL SAFETY WARNINGS

• 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.

BATTERY TOOL USE AND CARE

■ Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
■ Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
■ When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails,

screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

■ Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

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.

SELECTING SANDING BELTS

Selecting the correct size and type of sanding belt is an important step in achieving a high quality sanded finish. Aluminum oxide, silicon carbide, and other synthetic abrasives are best for power sanding.

In general, when sanding, coarse grit removes the most material and fine grit produces the best finish. The condition of the surface to be sanded determines which grit will do the best job. If the surface is rough, start with a coarse grit and sand until the surface is uniform. Then use medium grit to remove scratches left by the coarser grit. Finally, use finer grit for finishing the surface. Always continue sanding with each grit until the surface is uniform.

USING SANDING BELTS

See Figures 3 - 5, page 10.

To install/change sanding belts:

■ Remove the battery pack.
■ Position the sander on its side.

WARNING:

Keep hands and fingers clear of both rollers and spring mechanism at all times. Failure to do so could result in fingers getting pinched, causing serious injury.

■ Raise the tension release lever.
NOTE: If you are changing sanding belts, remove the old sanding belt at this time.
■ Install the sanding belt.

CAUTION:

If the sanding belt is not a bidirectional belt, ensure that the arrow inside the belt is pointing in the direction of the rotation (clockwise when looking into the open side of the sander). Installing unidirectional sanding belts backwards can create a hazardous condition.

■ Align the sanding belt to its correct position.
■ Lower the tension release lever to secure the sanding belt.

TO ADJUST SANDING BELT TRACKING

See Figures 6 - 7, page 11.

Belt life is greatly increased if you regularly adjust the sanding belt tracking. When correctly adjusted, the outer edge of the sanding belt should be even with the outer edge of the base of the sander.

When you install a new sanding belt, you may need to adjust the sanding belt tracking several times until the belt becomes conditioned.

WARNING:

Before connecting the sander to a power supply, always make sure it is not in the “locked-on” position. Failure to do so could result in accidental starting of the sander resulting in possible serious injury.

Follow these steps to adjust sanding belt tracking.

■ Insert the battery pack.
■ Position the sander upside down.
NOTE: This position is for adjustments only. The sanding belt should not contact a workpiece or any foreign object when you are making belt tracking adjustments.
■ Depress the switch trigger and release immediately.
■ Choose one of these options:
- Sanding belt runs inward: Turn the tracking knob slowly counterclockwise.
- Sanding belt runs outward: Turn the tracking knob slowly clockwise.

NOTE: Turn the tracking knob until you are sure the sanding belt is secure, i.e., it will not come off the sander or contact internal parts.

OPERATION

NOTICE:

If the sanding belt wears excessively on the inner edge it is probably adjusted too far inward and is rubbing against internal parts. If this is the case, readjust the tracking knob.

■ Start the sander and fine adjust the tracking knob until the belt stabilizes.

WARNING:

Keep hands and fingers away from a moving sanding belt. Any part of the body coming in contact with a moving sanding belt could result in serious injury. Do not wear loose clothing or jewelry when operating the sander. They could get caught in moving parts and foreign objects could get thrown away from the sander causing injury.

DUST COLLECTION BAG

See Figure 8, page 11.

WARNING:

Do not use the dust collection bag when sanding metal. Using the dust collection bag when sanding metal creates a fire hazard, which could damage the tool and lead to serious personal injury.

To attach the dust collection bag:

■ Remove the battery pack.
■ Slide the dust bag retainer over the blower exhaust hole on the sander.

For more efficient operation, empty the dust collection bag when it is no more than half full. This action permits the air to flow through the bag better. Always empty and clean the dust collection bag thoroughly upon completion of a sanding operation and before placing the sander in storage.

WARNING:

Collected sanding dust from sanding surface coatings such as polyurethanes, linseed oil, etc., can self-ignite in ther sander dust collection bag or elsewhere and cause fire. To reduce the risk of fire, always empty the dust bag frequently (10-15 minutes) while sanding and never store or leave a sander without totally emptying its dust bag. Also follow the recommendations of the coatings manufacturers.

To empty the dust collection bag:

■ Remove the battery pack.
■ Remove the dust collection bag from the sander.
■ Unzip the dust bag.
■ Shake out the dust.
■ Zip up the dust bag.
■ Replace the dust collection bag.

NOTE: Periodically, you should turn the dust bag inside out and thoroughly clean it.

ADJUSTING THE FRONT HANDLE

See Figure 9, page 11.

■ Remove the battery pack.
■ Depress the handle release button and move the handle until it locks into one of the five possible positions.

NOTE: Always make sure the handle is locked into one of the five lock positions.

- Secure the work to prevent it from moving under the sander.

WARNING:

Unsecured work could be thrown towards the operator causing injury.

■ Turn the sander on and let the motor reach its maximum speed before placing the sander on the work surface.
■ Lower the sander to the work surface with a slight forward motion.
■ Move the sander slowly over the work surface, using the rear handle to control the sander and the front handle to guide the sander.

NOTE: Allowing the sander to remain in one place will result in an uneven surface.

WARNING:

Keep a firm grip on the sander with both hands at all times. Failure to do so could result in loss of control leading to possible serious injury.

OPERATION

The sander is designed to provide the proper weight on the sanding belt. Excessive pressure will result in the following:

■ Uneven work
■ Clogged sanding belts
■ Premature sanding belt wear
■ Possible motor burnout
■ Irregular sanding belt tracking

PROPER HAND PLACEMENT

See Figure 11, page 11.

For ease of operation and maintaining proper control, the sander has a front handle and a rear handle. These handles allow two-handed operation, which aids in maintaining control, keeping the sanding area level with the workpiece, and keeping hands clear of the sanding belt. When operating the sander, always hold the front handle with your left hand and the rear handle with your right hand.

WARNING:

Keep hands and fingers clear of moving sanding belt, front idler roller, and drive roller assembly. Failure to do so will result in serious personal injury.

WARNING:

Do not let your fingers rest over the front or right edge of the sander. If the sanding belt should run off, or if it is not properly adjusted, your fingers could come in contact with the moving sanding belt, resulting in possible serious injury.

WARNING:

The sander is designed to be operated as shown with both hands on the tool at all times for maximum control. Never operate the tool overhead or inverted from the proper operating position; serious personal injury may result.

HELPFUL TIPS

If the sanding belt slips or does not track while sanding, you may be applying too much pressure. When this occurs, remove the sander from the workpiece. If you properly adjust the belt tracking, the sanding belt will return to its normal and correct position on the drive roller and front roller.
■ Use a coarser sanding belt for heavy sanding, not heavy pressure. The weight of the tool is sufficient to provide adequate pressure at the correct location.
■ The front roller of the sander is not designed for contour sanding. Sanding on the front roller could cause irregularity in the sanding belt tracking.
