Maintenance - Sealey Sm65.V3 Manual

DO NOT turn on the machine until the workpiece is secured and the blade has been lowered to just above workpiece.
8
5.1.7. Bring the blade into contact with the workpiece and then release the arm. If the blade jams and the saw does not automatically shut
off, immediately disconnect it from the power supply. Refer to the 'Troubleshooting' section for common problems.
5.1.8. When sawing is completed disconnect from the power supply, raise blade and remove workpiece.
WARNING! NEVER RAISE THE BLADE WHEN THE MACHINE IS RUNNING AND NEVER RUN

THE MACHINE WHEN THE BLADE IS RAISED.
6. ADJUSTMENTS
WARNING! BEFORE MAKING ANY ADJUSTMENTS, DISCONNECT SAW FROM POWER SUPPLY.
‰
6.1. BLADE TENSION
6.1.1. Disconnect the machine from the power supply and then remove blade cover.
6.1.2. ` Adjust the blade tension with knob (95) (fig.3.A), so that light thumb pressure on the blade midway
between the blade wheels produces a deflection of approximately 1mm. DO NOT over tighten.
6.1.3. Replace blade cover, reconnect to power source and run for two to three minutes to seat the blade.
6.1.4. Disconnect saw from the power source, remove blade cover and recheck tension. Replace blade cover.
6.2. BLADE GUIDE BEARING ADJUSTMENT
6.2.1. Correct guide bearing (fig.3.B) adjustment is important so that the blade runs smoothly and evenly
without twisting or snagging anywhere. Each of the outer guide bearings is mounted on an adjustable
eccentric bush.
6.2.2. Disconnect the machine from the power supply.
6.2.3. Loosen the bearing pivot lock nut while holding the pivot, immediately above the bearing, with
an open ended spanner.
6.2.4. Turn the pivot to adjust the bearing. The bearing should barely touch the blade (0.001" clearance).
6.2.5. Tighten the lock nut when satisfied with the bearing adjustment.
6.2.6. Adjust both outer guide bearings.
6.2.7. When satisfied that the adjustment is accurate, carefully turn the blade wheels by hand to see if the
blade snags or rubs at any point. Readjust bearing(s) if necessary.
6.3. BLADE GUIDE ADJUSTMENT
6.3.1. Disconnect the machine from the power supply.
6.3.2. Loosen hex bolt (fig.4.E) and pivot blade adjustment bracket (fig.4.F) until blade is perpendicular to
vice bed (103).
6.3.3. Retighten the hex bolt (fig.4.E).
6.4. REPLACING THE SAW BLADE
6.4.1. We recommend you keep a small supply of commonly used saw
blades to hand. Change saw blades frequently for best results.
Ensure you choose a blade with a pitch suitable for workpiece to be
cut (see cutting chart, Section 4).
WARNING! TAKE CARE WHEN HANDLING SAW BLADES,
‰
BLADE TEETH ARE VERY SHARP.
6.4.2. Loosen the blade tension, move both front guide bearings away from blade (see para. 6.2.) and remove blade cover.
6.4.3. Carefully remove old blade and install new one ensuring that tooth direction is consistent with the blade travelling left-to-right in the cutting
area.
6.4.4. Reset blade tension (see para. 6.1.), check tracking (see para. 6.5.), replace blade cover and adjust guide bearings (see para. 6.2.).
6.5. BLADE TRACKING
6.5.1. Adjustment of the blade tracking is necessary to prevent the blade from twisting or coming off the blade wheels. This adjustment
should be made whenever a new blade is fitted (see para. 6.4.).
6.5.2. Run saw for a short time and then switch off.
6.5.3. Raise saw arm, remove blade cover and check blade-to-wheel relationship (tracking). Rear edge of blade should be very close to, but
not hard against, the wheel flanges.
6.5.4. If inspection indicates that adjustment is required reduce blade tension (see para. 6.1.) and loosen the grub screw (65) in blade drive
wheel (67).
6.5.5. Move drive wheel in or out on shaft as required to improve tracking and tighten set screw.
6.5.6. Having made a small adjustment, tension blade, replace the blade cover, lower the arm and run the saw for a short time.
6.5.7. Switch saw off, remove blade cover and check tracking. Repeat adjustment procedure if necessary.
6.5.8. If the unit has a blockage of chips or work piece fragments, disconnect the machine from the power supply. While wearing protective
gloves use a brush or long handled wooden rod to remove the blockage.

7. MAINTENANCE

7.1. Clean saw after each operation and smear unpainted surfaces with oil to prevent rusting.
7.2. Annually replace gearbox oil (SAE 90) as follows:
7.2.1. With blade arm horizontal remove gearbox cover screws (16), cover (78) and seal pad (77).
7.2.2. Place oil container under right hand lower corner of gearbox and then carefully raise saw arm fully to drain oil.
7.2.3. Lower saw arm, remove any remaining oil from gearbox with clean cloths and then refill with fresh oil. Replace cover and gasket.
