6. adjustments
WARNING! Before following any of the steps below ensure the bandsaw is switched off, isolated from the electric power
supply and at a complete standstill. Failure to comply with this instruction can result in serious injury.
6.1.
B
LADE AND SPEED SELECTION.
6.1.1. refer to section 2 for the recommended setup for cutting various materials.
6.1.2. A good rule for blade selection is that 3 teeth should always be in contact with the workpiece, therefore,
the thinner the work
piece, the more teeth the blade should have.
6.2.
t
O ADJUST BLADE SPEED.
6.2.1. Disconnect the machine from the power supply.
6.2.2. Loosen the securing screw on the belt guard and lower the guard
6.2.3. release tension on the belt by turning the tension strut bolt anti-clockwise and letting the motor swing forward.
6.2.4. shift the belt to the desired grooves on the pulleys. Adjust the belt tension by pulling the motor plate back until correct tension is
obtained then tighten the tension strut bolt.
6.2.5. close the belt guard.
6.3.
t
O CHANGE BLADE AND ADJUST TENSION.
Caution: Blade teeth are sharp, handle with care.
NOTE:
Proper blade tension is very important to the safe and efficient running of the bandsaw. the correct tension for the
sm353cE.V2 is 2000kg/cm².
NOTE:
the
teeth must be pointing in the correct direction (indicated on the label found on the saw arm).
6.3.1. raise saw frame to the vertical position and close the feed control valve by turning clockwise as far as it will go (
DO NOT
overtighten).
6.3.2. open both wheel covers and clean the swarf out of the machine.
6.3.3. release blade tension by turning the blade tension handwheel anti-clockwise.
6.3.4. slide the left blade guide arm to the right as far as it will go.
6.3.5. remove the blade from both wheels and out of each blade guide.
6.3.6. Install the new blade, (teeth pointing down) on the blade wheels and through the upper blade guide, working all the way up between
the blade guide bearings with the back of the blade against the back-up bearing.
6.3.7. Put light tension on the blade and work onto both wheels. (Ensure the back of the blade is against the wheel flanges of both wheels).
6.3.8. Adjust blade to the final tension (2000kg/cm²). Proper tension is achieved by reference to the gauge on the stem of the tension wheel
(fig.13).
6.3.9. connect the machine to the power supply and turn it on and off two to three times to ensure
that the blade is seated and tracking properly. When finished close the wheel covers.
6.4.
H
YDRAULIC FEED ADJUSTMENT.
6.4.1. Adjust the hydraulic feed by turning the feed control on the control panel.
Anti-clockwise will increase the feed rate, clockwise will decrease it.
6.4.2. to stop the flow of hydraulic fluid, turn off the arm lock valve.
6.5.
t
O ADJUST THE BLADE GUIDES.
6.5.1. Loosen the adjusting handle on each blade guide and slide guide assemblies as close as
possible to each side of the workpiece and tighten.
6.6.
t
O ADJUST THE BLADE GUIDE BEARINGS. (fig.14).
6.6.1. raise the saw arm to a vertical position and close the arm lock valve.
6.6.2. Loosen the hex. cap screw on the guide assembly and adjust the rear bearing to 0.025 mm
from the blade.
6.6.3. Loosen lock nut and turn the front bearing eccentric so that bearing is snug with the blade. the
blade should still move up and down freely if grasped. repeat the procedure for the other guide
assembly.
6.7.
a
DJUSTING THE VICE.
NOTE: Do not adjust the vice or load/unload any material while the saw is running.
the vice can be adjusted to hold the
workpiece at angles between 0
°
and 45
°
.
6.7.1. to position the moveable vice jaw, turn the vice handwheel counter-clockwise half a turn and move the vice jaw to the desired position
and tighten using hand wheel.
6.7.2. Vice can be adjusted to cut any angle from 0° to 45° by loosening the two bolts on each vice jaw. Position the jaw to the desired angle
and tighten the bolts
6.7.3. When cutting at an angle, it is necessary to move the right vice jaw to the left until the workpiece and the right hand vice jaw are clear
of the right hand guide arm.
6.8.
t
O ADJUST BLADE TRACKING.
NOTE:
Blade tracking is factory set and should not require adjustment. However, if it does become necessary, proceed as follows:
6.8.1. run saw for a short time and then switch off.
6.8.2. raise saw arm, open 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.
6.8.3. If inspection indicates that adjustment is required tighten or loosen the screw (fig.15)
until it tracks properly.
6.8.4. Having made a small adjustment
close the blade cover
and run the saw for a short
time.
6.8.5. switch saw off, open blade cover and check tracking. repeat adjustment procedure
if necessary.
