3.3.3. Ensure that the grub screw E is not protruding into the hole for the lever. Lay the cable into the
cable slot in the side of the lever and slide the handle down onto the end of the lever until the grub
screw E is aligned with the screw fixing hole G. Insert a hex key into the grub screw and screw it
down into the lever.
3.4.
Fitting blade
3.4.1. Fully raise motor block by pushing control lever towards rear.
3.4.2. Remove screw (fig.4.1) and rotate blade guard towards the rear.
3.4.3. Remove blade retaining screw (fig.4.2) and blade flange (3).
3.4.4. Locate blade on drive face ensuring that rotation arrow on blade matches that on blade guard.
Refit flange and screw.
3.4.5. Rotate blade guard forward and refit screw (1). Confirm that guard will prevent fingers
touching blade.
3.5.
Fill coolant tank - see chapter 2 - Specifications. Confirm tap (fig 8.1) is open.
3.6.
Check sight-glass and visually confirm that there is oil in the gearbox.
3.7.
Pull control lever forward as far as possible, to lower blade, and confirm that blade is clear of saw
base in this position. If blade is touching base then adjust abutment screw (fig.3.B) to achieve
clearance. Note: Fig.3 shows typical abutment screw locations which vary slightly between models.
3.8.
Raise blade as far as possible and confirm that rear of motor is clear of base. If motor is touching
base then adjust abutment screw (fig.3.C) to achieve clearance.
3.9.
Confirm all tools have been removed from saw, main switch (SM225 fig.5.1, SM250/275 fig.6.1) is
‘Off’ and blade guard is in position.
3.10.
Connect mains lead to power supply, having confirmed that supply matches voltage/phases
as shown on motor plate.
SM250/275 - Confirm that Emergency Stop switch (fig.6.2) is in the ‘run’ position (out) and switch 3
is in position ‘1’.
3.11.
Turn main switch ‘On’ and operate switch button in control lever handle - motor will run. Confirm
motor stops when either the button is released or the main switch is turned ‘Off’ or (SM250/275)
the Emergency Stop is pushed. During this test confirm that blade is rotating in direction as shown
by arrow on guard and that coolant pump is operating.
Note: SM250/275 - Main switch is lockable to prevent unauthorised use.
4. OPERATING INSTRUCTIONS
FWARNING! Before sawing ensure you wear approved safety goggles, ear defenders, appropriate dust mask if saw generates dust
and safety gloves, and that all other safety instructions in chapter 1 are followed carefully.
4.1.
Securing workpiece.
4.1.1. Ensure the saw is switched off at the main switch and then secure workpiece in the base vice (fig.7.1).
We recommend that you place a block of wood (slightly narrower than the work piece) in the vice below the item to be cut to act as a support.
4.1.2. When cutting a long workpiece use additional supports along the length.
4.1.3. If multiple workpieces of the same length are required, screw end stop into vice base, secure with locknut and adjust to give the
appropriate length.
4.2.
The ‘On’ and ‘Off’ switch.
With saw connected to mains power supply turn on main switch. Start saw by depressing the button located in the handle (fig.7.2).
Release button to stop saw.
4.3.
Operating.
F
WARNING! DO NOT switch the saw on whilst the blade is in contact with the work piece. Bring the rotating blade to the workpiece.
4.3.1. The blade must be running at maximum speed and coolant flowing before attempting to lower the cutting edge onto workpiece.
4.3.2. Lower the blade slowly and smoothly towards the workpiece (avoid jerky movements).
4.3.3. Exert adequate downward pressure on the handle to allow cutting according to the type and size of the material you are working with.
Avoid subjecting the blade to excessive strain, always ease the blade down against workpiece (a harsh downward impact may break
the blade or damage the teeth).
Do not apply undue force on the handle in order to cut workpiece. Maintain a controlled cutting speed through the workpiece.
4.3.4. When cutting heavy material, move the blade intermittently through the workpiece with steady progression.
4.4.
Completing the cut.
4.4.1. When cutting is completed, carefully raise the blade to its full extent.
4.4.2. Release the button and wait until the blade has fully stopped before attempting to remove the workpiece.
4.5.
Mitre cutting.
To cut the workpiece at an angle the saw head must be adjusted.
4.5.1. SM225 -
to effect an angled cut, loosen the saw support clamp screw and rotate the saw/motor assembly to the required
angle, reading the graduated scale, up to a maximum of 45
4.5.2. Re-tighten the clamp screw and make the cut.
4.5.3. SM250/275 - to effect an angled cut, move the locking lever (fig.7.3 & fig.8.2) to position ‘2’ and rotate the saw/motor assembly to
the required angle, reading the graduated scale (fig.7.4), up to a maximum of 45
4.5.4. Move the locking lever back to position ‘1’ and make the cut.
