 Check for damaged parts before each use. Carefully check that the product will operate properly
and perform its intended function. Replace damaged or worn parts immediately. Never operate the
product with a damaged part.
 Do not use a product with a malfunctioning switch. Any power tool that cannot be controlled with
the power switch is dangerous and must be repaired by an authorized service representative
before using.
 Disconnect the power/air supply from the product and place the switch in the locked or off position
before making any adjustments, changing accessories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally.
 Store the hammer drill when it is not in use. Store it in a dry, secure place out of the reach of
children. Inspect the tool for good working condition prior to storage and before re-use.
 Use only accessories that are recommended by the manufacturer for use with your product.
Accessories that may be suitable for one product may create a risk of injury when used with
another tool. Never use an accessory that has a lower operating speed or operating pressure than
the tool itself.
 Keep guards in place and in working order. Never operate the product without the guards in place.
 Do not leave the tool running unattended.
Specific Operation Warnings
⚠WARNING
 To reduce the risk of injury, always wear eye protection.
 Wear ear protection with impact drills. Exposure to noise can cause hearing loss.
 Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
 Hold power tools by insulated gripping surfaces, when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
 When drilling or screwing into walls, ceilings, etc., make sure beforehand that you will not damage
any hidden electric cables. During this work you should not touch any metal parts of the machine;
only touch the machine by the plastic housing.
 Do not use fly cutters or multiple-part hole cutters, because they can come apart or become
unbalanced during use.
 Do not drill material too small to be securely held.
 Use only well-sharpened bits that are in good condition and appropriate for the task.
 Never use excessive force when drilling. Too much pressure reduces the speed of the machine,
and the required power is greatly reduced. This may result in an overload, which can damage the
motor of the drill. When the drill becomes too hot, allow it to run for two minutes without a load and
then interrupt working for a short time.
 Keep the motor running when pulling the bit out of a completed hole to prevent the bit from
jamming.
 When drilling large holes in metal, start by drilling a smaller pilot hole, then using a larger bit for
the final size hole.
 Never change the position of the forward/reverse switch while the chuck is turning.
 Always use a higher drill speed when drilling small holes. Use a slower drill speed when drilling
large holes.
 Ensure that the ventilation slits are not blocked.
