Blade guide settings
The machine has a freely moving lever to alter the
direction by lifting and turning it slightly. It allows you
quickly and easily to adjust the blade guide at any time.
The blade guide is adjusted in accordance with the
dimensions of the parts. Only the one on the left of the
cutting head can be adjusted; the other is fixed.
1. If the part is large, undo lever (A) of Fig. 7. Move the
guide by about 2.5 cm towards the part, then tighten
the lever again.
2. If you are cutting a small part bring the guide as
close as possible to the part. The two types of cut
will guarantee satisfactory accomplishment of the
work.
Adjustment where there is poor
cutting
The machine has been adjusted and subjected to
different cutting tests before leaving the factory to
ensure that it functions properly. If you discover that it is
cutting poorly, correct the defect by doing the following:
1. Poor cutting due to blade wear: put in a new blade.
2. The saw is equipped with fixed ball bearings.
To ensure correct cutting, we recommend to replace
them every three or six months, depending on the
frequency of use.
3. Poor cutting can be due to loosening of the
fastening nut (A). Tighten it again correctly.
Maintenance of the gear transmission
The gears of the transmission system fitted to the
machine are made of special steel.
The quality of these gears gives them superior strength
and durability. To keep the saw operating optimally, we
advise you to lubricate them every three months by
carrying out the following procedure:
1. Undo the screw (A) of Fig. 8 using an 8 mm Allen key.
2. Remove the wheel (B), then lubricate the gears
using thermostable grease.
3. Carefully re-assemble the wheel, and tighten the
screw correctly (A).
Adjusting blade tension
The tensioning system of the machine is designed to facilitate interventions. It is sufficient to turn control lever
(B) of Fig. 6 to increase or reduce the tension of the blade as needed, during operation. The main function of
this adjustment is to ensure perfect cutting as it allows the blade to work at a constant tension. A pair of
compression springs fastened to the tensioning system are there in addition to reduce the play of the blade.
All this contributes to prolonging the lifetime of the latter.
