2. Construction
The two speed hand drill DSk 672 is an electric tool of Class II
with protective insulation according to VDE regulations 0740.
Th e protective insulation is additional to the normal insulation
and separates all accessible parts of the metal casing f rom all
internal part s li ab le to become li ve.
Th e machin e must not be earthed and must be connected with
a two- core cable without ear th wire.
The drill is tested with the prescribed test voltage of 4000 V.
The machine is radio suppressed according to radio interference
degree N.
T
ype DSk 772 for low tension (42 V) is of th e same design but
not radio suppr es sed.
To prevent the overbridging of the insulation no additional
marking plates and signs must be riveted or screwed on the
housing. We recommend the use of transfers only.
3. Connection and operation
Main voltage m ust correspond to the operating voltage marked
on the rating plate. The tool ca n be plugged into plain or safety
so ckets.
Switch
must be in the "Off" position when connecting.

Th e sp ee d of the machine mus t only be changed at stand-still
or at slowing down without load. Release switch handle (54) of
its longitudinal position, put it across by turning it out, then
push it into the wanted switch direction and reset th e switch
handl e in oppos it e direction again into its longitud i nal position.
4. Maintenance
Before carrying out any maintenance work always remember
to pull out the plug.
Every 300 duty hours blow or brush o ut the t oo l with special
attention to carbon brush holders and insulated parts in order
to guara n tee the safety given by the protective insulation.
After checking the carbon brus h es make su re to refit them in
their original position and check that th ey mo ve eas ily in thei r
hold er. After fitting new bru sh es , run tool unload ed for about
15 minu tes to allow brush es to b ed in.
Worn carbon brushes automatically switch off the machine after
reaching the ir minimum len gth.
Please , only use original Fein ca rbon brushes .
In order to prevent acciden ts check cable and con nections at
both sides at regular int erva ls .
Aft er 900 duty hours th e machine should be completely dis-
mantled as described under paragraph 6 and all parts should

be thoroughly cleaned. Rinse ball bearings and gears in clean
solvent and pack with fresh grease as per paragraph 5.
Please be sure that all electric and plastic parts are only cleaned
dry.
5. Lubrication
W e recommend to renew the gear grease after 300 duty hours .
Please only use the Fein special grease FG 1. For ball and needle
bearings which should be lubricated after approx. 900 duty hours
we recommend our ball bearing grease FK 3.
The space between inner and outer ring is to be one third filled
with grease in order that the bearings do not overheat.
For good and adequate lubrication a nd to av oid overheating it
is important to pack gearing and bearings with the grades and
quantities of grease listed in the table below.
