3. SETTING UP THE SAW
3.1.1
Condition of saw blade. The best of saw blades will not cut efficiently if they are
not kept clean, sharp and properly set. Using a dull blade will place a heavy load
on your saw and increase the danger of ‘kickback’ (refer to section 4.1). It is good
practice to keep extra blades on hand so that sharp blades are always available.
Gum and pitch that has hardened on blades will slow the saw down. To remove
gum and pitch accumulations first remove the saw blade as described below and
use a gum and pitch remover, hot water or kerosene.
3.1.2
Remove any dust, rust preventative etc. and fit using only the supplied
flanges, washer and bolt.
3.1.3
Do not use a blade which is damaged, cracked, distorted or has missing teeth.
Do not use saw blades that are intended to cut steel.
3.1.4
Blade size - Ø184mm x 20 x 2.6 (24 teeth) The correct size and type of blade
must be fitted. The blade must not exceed 2.8mm in thickness as this may
prevent the outer blade washer from aligning with the flats on the spindle which
could in turn result in serious personal injury.
3.1.5
Unplug the saw from the mains power before changing the blade or performing
any maintenance.
3.1.6
CHANGING THE BLADE.
3.1.7
Place the blade wrench onto the outer flange nut to prevent the blade turning
then insert the hex key into the blade bolt and loosen it by rotating the key
anticlockwise as shown in fig.2.
3.1.8
Remove the bolt and washer together with the outer flange. Using the black tag
provided rotate the blade guard up into the blade housing and hold it there whilst
removing the blade with the other hand.
3.1.9
Fit new blade, ensuring that the teeth point in the same direction as the arrow
on the blade guard. Refit the flanges, washer and blade bolt, as shown in fig.3, and
tighten blade bolt using the hex key and wrench.
F
Important
!
Maintain original teeth angles when sharpening the blade.
!
After fitting a new blade start saw and allow to run for a few seconds. Watch
for blade wobble or vibration that would indicate incorrect installation or a
poorly balanced or damaged blade. Hold saw so that blade path is away from
body during this test.
3.2
DEPTH OF CUT ADJUSTMENT.
3.2.1
When setting the depth of cut the blade should not protrude more than 6mm below
the thickness of the material being cut. If the blade protrudes more than 6mm the
cut will be rough and there is an increased chance of ‘kickback’ occurring. (Read
section 4.1 regarding kickback.)
3.2.2
Before making an adjustment to the blade depth disconnect the saw from the
mains power.
3.2.3
Ensure that the workpiece to be cut is firmly held and cannot move.
3.2.4
To adjust the depth of cut take hold of the main handle of the saw and rest the
front edge of the saw base onto the workpiece so that the blade and blade guard
overhang the edge as shown in fig.5. (Do not allow the blade guard to operate)
3.2.5
Keeping hold of the main handle loosen the depth of cut adjustment knob (see
fig.4-A). Hold the base of the saw still as in fig.5 and move the whole saw
unit up or down through the fixed quadrant until the blade protrudes below the saw
base by the desired amount.
3.2.6
The depth of cut can be set by using the scale marked on the side of the
aluminium blade housing. The scale is marked from 0 to 65mm depth in
increments of 5mm. The markings on the housing should be aligned with the step
on the fixed quadrant where its width changes from broad to narrow. (See fig.4-B)
3.2.7
When the desired depth of cut is set tighten the adjustment knob.
3.3
ANGLE OF CUT ADJUSTMENT.
3.3.1
The saw can be set to cut at any angle from 0
the line of cut in relation to the base changes. At the front edge of the saw
base there are two triangular notches stamped out of the metal. One notch is
marked 0
and indicates the line of cut when the blade is vertical. The other notch
O
is marked 45
and indicates the line of cut when the blade angle is adjusted to 45
O
(See fig.10) If you wish to cut at any angle between 0
relation to the base assembly of the saw will vary. For this reason you should do a
trial cut on a scrap piece of material to establish the distance from the line of cut to
your guidance line.
3.3.2
Before adjusting the angle of cut disconnect the saw from the mains power supply.
3.3.3
To adjust the angle of cut loosen the forward and rear locking knobs as indicated in
fig.1. Lift the motor housing in relation to the base until the desired angle is
achieved as indicated on the scale stamped onto the forward locking knob
quadrant. (See fig.6). Tighten the forward and rear locking knobs.
3.4
DUST EXTRACTION.
3.4.1
In normal use the dust is discharged from the extraction port as indicated in fig.1.
Where a vacuum extraction system is available the dust extraction nozzle shown
in fig.1 should be inserted into the extraction port provided and this can then be
connected to the vacuum extraction system.
