protective eye wear that meets ANSI
Specification Z87.1
Disconnect the cut-off saw
from its electrical power source.
Tools required:
-- 3mm, 4mm and 5mm hex wrenches
-- 12mm wrench
Removing the Blade
1. Lock the hydraulic cylinder that controls the
descent of the saw head with the feed rate
start/stop control (F, Fig. 4). Raise the saw
head (A) about half way up.
2. Remove the wheel cover (B) and blade
guards (C, D) and brush (M).
3. Turn the blade tension handle (J) counter-
clockwise until the blade (E) hangs loose.
4. Pull the blade (E) off the drive wheel (F) and
idler wheel (G) and out of the blade guides
(H
1
, H

). Store the removed blade carefully
before proceeding.
Installing New Blade
5. Slide the new blade into the blade guides
(H
1
, H

), then loop the blade (E) around the
drive wheel (F) and idler wheel (G) such that
the teeth face towards the rear of the saw
and the smooth side faces towards the front.
6. Push the blade so it seats against the
shoulders of the wheels (F, G).
Adjusting the proper Blade Tension
7. When it is seated against the shoulder, turn
the blade tension handle (J) clockwise to
increase the tension until the scale for the
1" blade tension measures 20–28KPSI (K)
(green zone) on the tension indicator (L).
8. Replace the wheel cover (B) and blade
guards (C, D) and brush (M).

source.
