2. Construction
The hack saw ASt 636 is an electric hand tool of Class II in ac-
cordance with the VDE regulations 0740. In addition to the nor-
mal insulation the tool is equipped with a further protective in-
sulation which protects the user from electric accidents that may
arise from a wrong normal insulation. The shockproof motor
housing made of Polyamide forms the insulation of the pole
housing, whereas the live parts of the armature are separated
from the driving shaft by an intermediate insulation. The ma-
chine is supplied with a two core cable without earthing con-
ductor and must not be earthed. The insulation is tested with
the prescribed test voltage of 4000 Volts. The machine is radio
suppressed in accordance with radio interference degree N.
Type ASt 736 (42 V) is of the same design but not double insu-
lated. It must only be connected with a two-core cable without
earth wire.
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
Before plugging in the tool check that voltage stated on the rat-
ing plate is in accordance with the voltage of the mains supply.
Switch must be in the "Off" position when connecting.

Unscrew handle (60) combined with the hexagon pin and open
screw (51) on plunger (37). Put saw blade chosen for the work-
piece into the slot of the plunger and clamp with pin of handle
(60) and screw (51).
Usually the cutting table (52) is screwed so that the vaulted
side points into the cutting direction. In special cases and for
placing reasons e. g. if you want to cut near a vertical wall the
table can be turned by
180
°
and screwed.
The ventilation air blows the saw-dust away from the saw-blade
so that the tracing line is always visible.

Maintenance
Before carrying out any maintenance work always remember
to pull out the plug.
To guarantee the security given by the protective insulation
the machine must be cleaned regularly after
300
duty hours.
Blow or brush out the tool with special attention to carbon
brush holders and insulated parts.
For the checking of the carbon brushes take out carbon brush
holders
(10)
after unscrewing the screws
(12).
After checking the
carbon brushes be sure to lodge them in their original position
and check that they move with ease in their holders. They should
be replaced at the latest when they have worn down to the
