Specifications

NOTE: ALL blades can be re-
sharpened. If not excessively worn.
6. OPERATION
6.1 Setup
The AS170 is supplied ready for operation. However
in some cases the blades may need to be changed
to suit the application.
Before changing
blades, the guard
around the blade
mounts must be levered
gently out of its groove
at the front of the tool
and swung away to
give access to the cap
screws. (See Fig.1)

Use the “Ian key”
supplied to loosen and
remove the cap screws
securing the blades,
then remove the blades
as shown in fig.2.

Select the correct blades for the cutting task and
mount each with their cap screws . Verify that the
surfaces of the blade mounts, conrod thread and
screws are clean and free of grit or lubricant before
fitting. Ensure the guard can be closed before fixing
the blades to the conrod (See fig.2).
NOTE: Always use matched pairs of blades.
Never mix used blades with new blades. Use only
the bolts supplied with the tool.
Use the “Ian key” (see
fig.2), to tighten the
blade mounting screws
until the torque indicator
coil deflects sufficiently
so that the sides meet.
The “Ian Key” will
tighten the bolts to the
required 16Nm (11.5
ft lb).

NOTE: Blades are a wearing part. In normal
operation, blade life may vary with the hardness
of materials cut.
CAUTION:
Do not operate the tool
if the blades are loose.
Operation with loose
blades will severely
damage the blade
mount & bolts requiring
repair.
Check that the teeth of
the blades are lightly
contacting, or within
approximately 1mm
(1/16”) of contacting
each other (fig.4).

If the gap between the blades is too large, remove
and gently bent inward to adjust the gap.
Ensure that both blades are aligned vertically to the
tool (See fig.4).
CAUTION: If the blades rub against each
other anywhere other than within 20 mm/1”
of the cutting edge, or contact force is high,
it is possible to overload the tool and cause
premature belt wear.
Swing the guard to its groove at the front of the
tool and snap it into place. (See fig.1)
6.2 Operation
CAUTION: During
operation the AS170
may cause hand-arm
vibration, which can result
in fatigue or discomfort
after long periods of
continuous use. Vibration
will increase with the
hardness of material.
Do not operate the
tool if discomfort is
experienced, and ensure
that sufficient rest periods
are taken during cutting.
For further information,
contact the manufacturer.

that the safety section of this manual has been
consulted.
Apply protective hearing, breathing, eyes and body
