Replacement, Tensioning And Adjustment Of The Saw Blade - Pilous ARG 200 plus Instruction Manual

4.7. Replacement, Tensioning and Adjustment of the Saw Blade

A timely replacement of the saw blade is needed to achieve good cutting performance, surface finish quality and compliance with
workpiece dimensions. Blunt saw blades cause high consumption of electrical power, uneven cuts and rough cutting surfaces. One
of the decisive factors affecting the quality of the cut and the life of the cutting tool is a correct and sufficient saw blade tension.
Switch off the MAIN SWITCH or disconnect the machine from the mains and secure it against restarting. Close the oil damper relief
valve (see Section 4.2.) and raise the arm to about 20 mm above the fixed jaw of the vice. Remove the protective covers of the saw
blade and open/remove the back cover of the arm (see section 4.6.), if necessary lift the arm about 20 mm above the fix camping jaw
again. Use the tensioning star nut to loosen the tensioning wheel and the whole blade. Take the saw blade off the wheels and push it
off the guide heads (see Section 4.8.). Insert the new saw blade in the guide heads. Put it on the wheels and tension the saw blade by
a tensioning star nut. Tension the star nut, so that the disc springs are fully compressed (no light coming through)! In this
way, you can achieve correct tensioning of the saw blade. Install the protective covers of the saw blade and close the back cover
of the arm. Turn on the power switch or connect the machine to the mains and switch the machine to the minimum blade speed.
Switch on the saw blade START button to let the saw blade run approx. once through and make sure that the saw blade is correctly
aligned in the guide heads. Restart the saw blade with the START button and let it turn once. Switch off the MAIN SWITCH or
disconnect the machine from the mains and secure it against restarting. Remove the protective covers of the saw blade and
open/remove the back cover of the arm, and make sure that the saw blade is correctly fitted on the guide heads and correctly installed
on the blade wheels (see figure). If the saw blade is not correctly placed on the wheels, loosen the tensioning star nut and, using the
wheel tilt adjusting screw, adjust the position of the saw blade on the wheel (see the picture). Tension the star nut, so that the disc
springs are fully compressed (no light coming through)! Install the protective covers of the saw blade and close the back cover of
the arm. Turn on the MAIN SWITCH or connect the machine to the mains. Carry out a saw blade trial run. Turn off the MAIN SWITCH
or disconnect the machine from the mains, remove protective covers of the saw blade and open/remove the back cover of the arm.
Check the placement of the saw blade on the wheels. Repeat the procedure, if required. For a quick check of saw blade positioning
on the wheels, you can use the BLADE GUIDANCE CONTROL OPENING. Install the protective covers of the blade, close the back
cover of the arm and turn on the MAIN SWITCH. Carry out the cutting.

Caution: You can remove protective covers only if the MAIN 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 wheels and the saw blade.
