Before each use
1. Inspect the hammer drill, the trigger switch, the cord and the accessories for damage.
2. Check for damaged, missing, or worn parts.
3. Check for loose screws, misalignment or binding of moving parts, or any other condition that may
affect the operation.
4. If abnormal vibration or noise occurs, turn the tool off immediately and have the problem
corrected before further use. Unplug the tool from power source before cleaning or performing
any maintenance. Using compressed air may be the most effective cleaning method. Always wear
safety goggles when cleaning tools using compressed air.
WARNING!
Do not allow brake fluids, gasoline and petroleum-based products, penetrating oil, etc.
to come into contact with plastic parts. These substances contain chemicals that can
damage, weaken, or destroy plastic.
WARNING!
When servicing, use only identical replacement parts. The use of any other parts may
create a hazard or cause damage to the product.
WARNING!
If the supply cord of this power tool is damaged, it must be replaced by a specially
prepared cord available through the service organization.
WARNING!
Use only accessories that are recommended for this hammer drill by the manufacturer.
Accessories that may be suitable for one tool may become hazardous when used with
another tool.
WARNING!
Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools
with sharp cutting edges are less likely to bind, and are easier to control.
WARNING!
To ensure safety and reliability, all repairs should be performed by a qualified service
technician.
DRIllING IN WooD
For maximum performance, use high-speed steel or brad-point bits for wood drilling.
1. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
2. Increase the speed as the drill bit enters the material.
3. When drilling holes all the way through the workpiece, place a block of wood behind the workpiece
to prevent ragged or splintered edges on the back side of the hole.
DRIllING IN METAl
For maximum performance, use high-speed steel bits for metal or steel drilling.
1. When drilling metals, use light oil on the drill bit to keep it from overheating. The oil will prolong the
life of the bit and increase the drilling action.
2. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
3. Maintain a speed and pressure that allows cutting without overheating the bit. Applying too much
pressure will:
• Overheat the hammer drill
• Wear the bearings
• Bend or burn the bits
• Produce off-centre or irregularly-shaped holes
DRIllING IN MASoNRy
For maximum performance, use carbide-tipped masonry bits when drilling holes in brick, tile, concrete, etc.
1. Maintain a speed and pressure which allows cutting without overheating the bit or drill. Applying
too much pressure will:
• Overheat the hammer drill
• Wear the bearings
• Bend or burn bits
• Produce off-centre or irregular-shaped holes
2. Apply light pressure and medium speed for best results in brick.
3. Apply additional pressure for hard materials such as concrete.
4. When drilling holes in tile, practice on a scrap piece to determine the best speed and pressure.
Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
