Protective elements and their
assembly
The grinder may be used with mounted protective guard only!
Attention! Prior to handling the accessories, the pow-
er supply cable has always to be disconnected from
the power source socket!
Protective guard
Attention! The protective guard intended only and ex-
clusively for work with the grinding wheels is the inte-
gral part of the standard angular grinder outfit.
When cutting, the angular grinder has to be equipped by the pro-
tective guard intended for work with the cutting wheels; it can be
purchased in the trade network under the order No. 00 763 304 for
dia. 230 mm. Failing to use the guard for cutting, you run the in-
creased risk of injury and in this case (non-use of the special guard
for cutting) the company Narex is not liable anyhow for possible
harm of health of the user or another person injured as the conse-
quence of breach of the safety rules.
Loosen the fixing lever (11). Put the protective guard (9a; 9b) on
the clamping collet (6). The guide lug (10) must be inserted into
the groove on the clamping collet. Set the protective guard (9a;
9b) to the requested working position and fix the collet, using the
fixing lever (11). For safety reasons the clamping bolt (12) must be
tightened firmly by the torque 3+0,5 Nm.
Additional handle VIBRASTOP
Special construction regulates the vibrations with auxiliary han-
dle (5). Auxiliary handle can be screwed from the left or right side
of gearbox (4). Some operations may require the handle screwed
to the top of gearbox.
Autobalancer (self-balancing assembly)
Autobalancer (18) is pressed on the grinder spindle by the manu-
facturing plant and other angular grinders cannot be equipped by
the Autobalancer additionally. By its design Autobalancer reduces
the vibrations generated as the consequence of wheel disbalance,
thus protecting the operator from their harmful impact effectively.
Note: Autobalancer (18) replaces the bottom flange.
Adjustable main handle
By rotating the main handle (21), the design of which enables to
swivel the main handle in the longitudinal machine axis to three
positions (0° – initial position; +90° and -90°), the operator can
take comfortable position for work enabling permanent control of
grinder controllers.
To set the main handle (21) to the requested position, the un-
lock button (22) has to be depressed and then the handle can be
swiveled in the longitudinal grinder axis in one of three available
positions. After automatic unlock button click the handle is fixed
firmly in the chosen position.
