6. OPERATION
6.1 Setup
The AS160 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 Hex 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 of any kind before mating
them. 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.
•
Tighten the blade mounting screws to the Specifications in
section 9. If
using the special ‘Ian key’, tighten the blade mounting screws until the
torque indicator coil deflects sufficiently so that the sides meet. Using
the Ian Key in this manner will tighten the bolts to the required
16nm.
CAUTION: Do not operate the tool if the blades are loose. Operation
with loose blades will severely damage the blade mount & bolts
requiring repair at a service centre.
•
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, as may be the case after some use,
they can be removed 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)
