DRILLING WITHOUT IMPACT
Materials like steel, wood and plastics can be drilled with rotary hammer with the use of three jaw chuck
with intermediate adapter. Assemble together three jaw chuck and adapter by twisting and then place it in
the rotary hammer chuck (proceed like with SDS-PLUS drills) (fig. D).
Use drills made of high speed steel or carbon steels (only for wood and wood-like materials).
Do not use three jaw drill chuck when the rotary hammer drill is set to impact drilling. This chuck is
designed for regular drilling only (in wood or steel).
Unplug the power cord from the mains socket before commencing any activities related to installa-
tion, adjustment, repair or maintenance.
●
Always keep the rotary hammer drill clean.
●
Never use any caustic agents for cleaning plastic parts of the rotary hammer drill.
●
After operation use compressed air to blow through the rotary hammer drill to remove dust deposit,
especially to keep ventilation slots pervious.
●
It is necessary to regularly check technical condition of carbon brushes of the electrical motor (dirty or
used up brushes can cause excessive sparking and loss of spindle speed of the rotary hammer drill).
REPLACEMENT OF CARBON BRUSHES
Replace immediately worn out (shorter than 5 mm), burnt or cracked motor carbon brushes. Always
replace both brushes at a time.
Entrust replacement of carbon brushes only to a qualified person. Only original parts should be used.
All faults should be repaired by service workshop authorized by the manufacturer.
