Screwdriving operation
CAUTION: Adjust the adjusting ring to the
proper torque level for your work.
CAUTION: Make sure that the driver bit is
inserted straight in the screw head, or the screw
and/or driver bit may be damaged.
Placethepointofthedriverbitinthescrewheadandapplypres-
suretothetool.Startthetoolslowlyandthenincreasethespeed
gradually.Releasetheswitchtriggerassoonastheclutchcutsin.
NOTE: When driving wood screw, pre-drill a pilot hole
2/3thediameterofthescrew.Itmakesdrivingeasier
and prevents splitting of the workpiece.
Drilling operation
First,turntheadjustingringsothatthearrowpointsto
the marking. Then proceed as follows.
Drilling in wood
Whendrillinginwood,thebestresultsareobtainedwith
wood drills equipped with a guide screw. The guide screw
makesdrillingeasierbypullingthedrillbitintotheworkpiece.
Drilling in metal
Topreventthedrillbitfromslippingwhenstartinga
hole, make an indentation with a center-punch and
hammeratthepointtobedrilled.Placethepointofthe
drillbitintheindentationandstartdrilling.
Useacuttinglubricantwhendrillingmetals.Theexcep-
tionsareironandbrasswhichshouldbedrilleddry.
CAUTION: Pressing excessively on the tool
will not speed up the drilling. In fact, this excessive
pressurewillonlyservetodamagethetipofyourdrill
bit,decreasethetoolperformanceandshortenthe
service life of the tool.
CAUTION: Hold the tool rmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
thetool/drillbitatthetimeofholebreakthrough.
CAUTION: A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it rmly.
CAUTION: Always secure workpieces in a
vise or similar hold-down device.
CAUTION: If the tool is operated continuously
until the battery cartridge has discharged, allow
the tool to rest for 15 minutes before proceeding
with a fresh battery.
MAINTENANCE
CAUTION: Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
NOTICE: Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
TomaintainproductSAFETYandRELIABILITY,
