Setup And Adjustments; Changing Sawblade; Saw Blade Selection; Miter Adjustment - Promac MCS-275 Mode D'emploi

Coolant system:
Use the coolant facility to keep cutting
temperatures down, reduce friction and
extend the life of your sawblade.
Make sure the cutting liquid is properly
contained to the machine.
Use only water soluble cutting
emulsions and dispose of it in an
environmentally friendly manner.
The coolant flow control valve (Fig 4) is
located on the back of the saw. Adjust
the valve to achieve desired flow.
Fig 4
Coolant should be changed regularly.
Feeding speed:
Thin-walled materials such as tubes or
thin profiles must be cut with a low
feeding speed.
A new saw blade requires a break-in
period, during which time about half the
normal feeding speed should be used.

7. Setup and adjustments

General note:
Setup and adjustment work may only
be carried out after the machine is
protected against accidental starting by
pulling the mains plug.

7.1 Changing sawblade

Disconnect the machine from the power
source.
The sawblade has to meet the technical
specification.
Check sawblade for flaws (cracks,
broken teeth, bending) before
installation. Do not use faulty
sawblades.
Always wear suitable gloves when
handling sawblades.
Remove the screw (A, Fig 5) and cover
plate (B).
Fig 5
Remove the socket head cap screw (C).
Raise the lower blade guard (E) upwards
(F).
Remove socket head cap screw (G).
Note:
This screw (G) has a left hand thread.
Remove the blade (H) and outer flange
(J).
Place new blade and make sure the
teeth are pointing the cutting direction.
Note:
The flange (J) has a pin (K) that needs to
match up with the correct keyhole (L).
Place a few drops of lightweight oil on
the blade.
Install parts in reverse order.
Connect to the power source.

7.2 Saw Blade Selection

Take care that the selection of the saw
blade depends on the material and
profile to be cut.
Fig 6
Fine Tooth Pitch:
- For thin wall materials ( tubes and
profiles)
Coarse Tooth Pitch:
- For large cross-sections
- For soft materials (aluminium)
When cutting thick material, a coarse
Tooth Pitch "T" is needed to
accommodate the big chips (Fig 7)
Fig 7

7.3 Miter adjustment

The saw arm can be adjusted for square
and mitre cuts.
Loosen the miter lock handle (H, Fig 8)
and move saw arm to the desired angle.
