4.3. HYDRAULIC FEED SELECTOR OPERATION.

4.3.1. The rate of descent of the main cutting arm is controlled by the

damping cylinder seen in fig.1. By turning the knob ‘F’ in fig.1

clockwise the rate of descent is slowed down. By turning the

knob anticlockwise the rate of descent is increased. The arm can

be locked in any position by turning the hydraulic flow off using

tap ‘G’ in fig.1. When the tap is at 90° to the cylinder the flow is

off and the arm will stop moving.

4.4. VICE SET UP & ADJUSTMENT.

4.4.1. The vice has two adjustment positions. One specifically set at

90° degrees to the blade (see fig.3) and the other for variable

angle cutting (see fig.4).

4.4.2. For a non angled cut the vice should be set up as shown in fig.3.

Loosen pivot bolt ‘J’ and locking nut ‘B’ and adjust the vice face

to be 90° degrees to the blade by laying a set square onto the

machine bed as shown in fig.5. Tighten pivot bolt ‘J’ and locking

nut ‘B. When locking bolt ‘F’ is loosened the distance between

the vice faces can be adjusted by winding handle ‘G’. Adjust the

position of the stock stop ‘E’ as required. Lay the material to be

cut into the vice and wind handle ‘G’ until the material is firmly

clamped between the vice faces. Tighten locking bolt ‘F’.

4.4.3. To change the set up to an angled cut the vice should be

configured as shown in fig.4. Remove locking nut ‘B’ and its

associated bolt from straight slot ‘A’ and reassemble them into

the curved slot ‘C’. Referring back to fig.3 move the pivot bolt

‘J’ to position ‘K’ on the bed. The vice face will now pivot around

bolt ‘J’. Set the vice face to the desired angle using an adjustable

square and lock it at the set position with nut ‘B’ as shown in

fig.4. Lay the material to be cut into the vice and wind handle ‘G’

until the material is firmly clamped between the vice faces.

Tighten locking bolt ‘F’.

4.5. ADJUSTING BOW WEIGHT.

4.5.1. Bow weight is one of the most important adjustments on the saw.

Incorrect bow weight can result in poor performance including

crooked cuts, tooth stripping, stalling and the blade coming off the

blade wheels. The hydraulic feed rate unit will not compensate for

improper bow weight. Bow weight is factory set and should not

normally require adjustment. If performance problems are

encountered the bow weight can be adjusted as follows:

4.5.2. The bow weight spring, which acts on the main arm, can be seen

in fig.4.H as can the adjuster nuts fig.4.I

4.5.3. Disconnect the saw from the power supply.

4.5.4. Turn the hydraulic cylinder valve on and place the arm in the

horizontal position.Turn the feed rate valve on the cylinder

anticlockwise until it stops.

4.5.5. Hook a spring balance under the blade tension handle and lift the

saw arm. The scale should read 5-6kg. If this is not he case

adjust the tension until it does.

4.2. CHANGING BLADE SPEED.

4.2.1. Disconnect the machine from the power supply.

4.2.2. Remove the pulley cover screw and hinge up the cover to access the

pulleys and belt.

4.2.3. Loosen the lock bolt on the rear of the motor plate as shown in

fig.2.3.

4.2.4. Loosen the locking nut on the tensioning screw as shown in fig.2.2.

4.2.5. Loosen the tensioning screw itself (see fig.2.1) and slacken it off in

order to allow the motor plate to move inwards to shorten the

distance between the two pulleys. It may be necessary to tap the

edge of the motor plate with a soft faced hammer to get the plate to

move inwards to the point where the belt position can be changed.

Refer to the adjacent diagrams to decide on the best position for

the belt for the job in hand.

4.2.6. When the belt is repositioned, retension it ensuring that it is not too

tight and tighten the motor plate lock bolt. Close the pulley cover

and replace the cover screw.
