Arm - Saw Blade Guidance - Pilous ARG 330 SAF Instruction Manual

4.5. Arm - saw blade guidance

The arm of the ARG 330 S.A.F., ARG 330 plus S.A.F. and ARG 400 plus .S.AF. is made of a robust casting from grey cast iron.The
casting is hollow, which ensures extraordinary stiffness when tensioning the saw blade. The arm of the ARG 380 plus S.A.F., ARG
500 plus S.A.F. is a massive welded steel structure. The saw blade is guided by two guide heads both behind and in front of the cut.
The heads are fitted with eccentrically placed bearings and hardened steel blade guides that allow easier rewinding of the saw blade
as opposed to wheel guidance. The fixed guide block is placed on a fixed guide bar and the movable guide block is placed on the
movable bar. The moving guide block moves towards the cut material by 30-50 mm manually.
Danger of injury - no cover in the machining area!

you want to put the cover back on the machine, use a reversed procedure.
Turn on the POWER SWITCH and the hydraulic unit.
S.A. MODE - the arm is situated in between the limit switches, therefore it is necessary to switch the ARM END STROKE SWITCH
into position 1 and the arm will travel to the upper position. Now you can start cutting and the descent; press the green button START
and the semi-automatic cycle will start.
MANUAL MODE - press the SAW BLADE UPWARDS button and the arm will also travel into the upper position; or press the SAW
BLADE DOWNWARDS button and the arm will travel to the lower position (ARM END STROKE SWITCH must be set in position 0).
Caution: You can remove protective covers only if the power switch is turned off and
secured against restart or if the machine is disconnected from the mains.
Caution: Danger of injury by the sharp teeth of the saw blade. Use protective gloves.
Do not reach between the running wheels and the saw blade.
