START DRILLING
- Start the tool by squeezing the variable speed trigger switch.
- Release the trigger to stop the tool.
HOLE DRILLING
When attempting to drill a large diameter hole, it is sometimes best to start with a smaller drill bit then work up to
the required size. This prevents overloading the drill.
WARNING: Many accidents occur because of unforeseeable situations. Please pay attention that drilling-
out a small hole may cause the drill bit to jam in the hole, especially when drilling metal.
- Remember to use a "wood-pecker" action on deep holes to allow the swarf to be ejected from the hole.
- If the drill bit snags, switch off immediately to prevent permanent damage to the drill.
- Try running the drill in reverse to remove the bit.
- Keep the drill in line with the hole. Ideally, the drill bit should enter at right angles to the work. If the angle
is changed during drilling, this could cause the bit to snap off, blocking the hole and perhaps causing injury.
- Reduce pressure as the drill is about to break through the item being drilled.
- Don't force the drill, let it work at its own pace.
- Keep the drill bit sharp.
DRILLING WOOD
For maximum performance when drilling larger holes, use auger bits or spade bits for wood drilling.
- Set the tool to the drill mode.
- Begin drilling at a very low speed to prevent the bit from slipping off the starting point. Increase the speed
as it bites into the wood.
- When drilling through holes, place a block of wood behind the work piece to prevent ragged or splintered
edges on the back of the hole.
DRILLING METAL
For maximum performance, use HSS drill bits for metal drilling.
- Set the tool to the drill mode.
- Mark off the center of the hole using a center punch.
- Use a suitable lubricant for the material you are working on.
- Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
- Always clamp sheet metal. Support thin metal with a block of wood to avoid distorting it.
DRILLING CONCRETE
For maximum performance, use high quality carbide-tipped masonry drill bits when drilling holes in brick, tile,
concrete etc.
- Use the drilling mode initially then revert to the impact mode once the holes are established.
- Apply light pressure and medium speed for best results in brick.
- Apply additional pressure and high speed for hard materials such as concrete.
- When drilling holes in tile, practice on a scrap piece to determine the best speed and pressure.
NOTE: Reverse rotation during impact drilling may damage the drill and drill bit.
MAINTENANCE
WARNING: Do not allow brake fluids, gasoline, petroleum-based products penetrating oils, etc... come in
contact with plastic parts. They contain chemicals that can damage, weaken or destroy the housing, thus
compromising the integrity of of the double insulation
WARNING: Always disconnect the device before performing any adjustment or maintenance operation. If the
supply cord is damaged, it must be replaced by the manufacturer or its service agent in order to avoid a
hazard. Disconnect from the power supply immediately if the supply cord is damaged. Take care not to expose
this tool to the rain. If the carbon brushes need to be replaced, have this done by a qualified repair person (always
replace the two brushes at the same time) Your power tool requires no additional lubrication or maintenance. Never
use water or chemical cleaners to clean your power tool. Wipe clean with a dry cloth. Always store your power tool
in a dry place. Keep the motor ventilation slots clean. Keep all working controls free of dust. Occasionally you may
see sparks through the ventilation slots. This is normal and will not damage your power tool. The ambient
temperature range for this tool use is 0ºC - 40ºC. The relative humidity of the area must be not more than 80%
without direct exposure to rain and excessive dust content of the air There are some user serviceable parts in your
power tool. Please refer to the list of spare part list of the manual
