1. Select the high speed (2) setting by sliding the gear shifter (D) back (away from
the chuck). Turn the collar (C) to the hammerdrill symbol.
IMPORTANT: Use carbide-tipped or masonry bits rated for percussion drilling
only.
2. Drill with just enough force on the hammer to keep it from bouncing excessively
or "rising" off the bit. Too much force will cause slower drilling speeds,
overheating, and a lower drilling rate.
3. Drill straight, keeping the bit at a right angle to the work. Do not exert side
pressure on the bit when drillling as this will cause clogging of the bit flutes and a
slower drilling speed.
4. When drilling deep holes, if the hammer speed starts to drop off, pull the bit
partially out of the hole with tool still running to help clear debris from the hole.
NOTE: A smooth, even flow of dust from the hole indicates proper drilling rate.

MAINTENANCE
WARNING: To reduce the risk of serious personal injury, turn the tool off and
disconnect the battery pack before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can cause injury.
Cleaning
WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once
a week. To minimize the risk of eye injury, always wear AS/NZS1337 approved eye
protection when performing this.
WARNING: Never use solvents or other harsh chemicals for cleaning the
non-metallic parts of the tool. These chemicals may weaken the plastic materials
used in these parts. Use a cloth dampened only with water and mild soap. Never let
any liquid get inside the tool; never immerse any part of the tool into a liquid.
