!
WARNING!
Protect your hands with gloves when working with the blades.
There is a risk of crush injuries when working with the belt.

the bolt to the parallelism handle (2), and
the two screws on the cover (3). Lift the
protective cover from the belts.
3. Loosen the spring (4) that tensions the
V-belt and wriggle the belt off.
4. Attach the new belt.
The belt tightening schedule is located
on a decal on the inside of the protective
cover.
5. Check that the belt tensioning equipment
is not jammed or binding and replace the
spring.
6. Replace the protective cover and attach
the parallelism handle and unit frame.
7. Attach the cutting unit to the machine, see Attaching the Cutting Unit on page 38.
