Unlatching And Raising The Cutting Head; Installing Or Removing A Blade; North American Models - Evolution R255 SMS-DB Notice Originale

Note: The cable should not be stretched or
taught anywhere along its length. (Fig. 21)
Raise and lower the cutting head several times
(see the section below - 'Unlatching and Raising
the Cutting Head') and also operate the sliding
carriage. Check that the cable does not become
entangled with any other parts of the machine.
Check also that the cable is not stretched during
any of the operating procedures. To secure the
cable, secure the cable using the cable clip.
Note: The cable guides can be used to provide a
very convenient way of storing the mains cable
on the machine when the machine itself is not
being used and is perhaps in storage.
UNLATCHING AND RAISING THE
CUTTING HEAD
(Fig. 22)
WARNING: To avoid serious injury, NEVER
perform the locking or unlocking procedure
unless the saw is OFF and the blade stationary.
To release the cutting head from the locked down
position:
• Gently press down on the Cutting Head Handle.
• Supporting the head, pull out the head latching
pin (Step 1) and allow the cutting head to rise
to its upper position.(Step 2)
Note: The cutting head will automatically rise to
the upper position once it is released from the
locked down position. It will automatically lock in
the upper position.
If release is difficult:
• Gently rock the cutting head up and down.
• At the same time twist the Head Latching Pin
clockwise and pull outwards.
Note: We recommend that when the machine is
not in use the cutting head is locked in its down
position with the latching pin fully engaged in
the open half socket which is machined into the
cutting head upper surface near to the pivot
point. (Fig. 23).

Note: It is recommended that the operator
considers wearing protective gloves when
handling the blade during installation or when
changing the blade.
Ensure the cutting head is in its upper position.
(Fig. 24)
• Remove the blade arbor cover by unscrewing
the 2 screws with a crosshead screwdriver.
(Fig. 25)
• Rotate the lower blade guard up and into the
upper blade guard (Fig. 26 - step 2).
Note: Lowering the cutting head slightly will
allow the lower blade guard to rotate fully into the
upper blade guard giving maximum access for the
operator.
• Press the black arbor lock button to lock the
arbor. (Fig. 27) You may need to rotate the
arbor slightly for the arbor lock to engage.
• Using the supplied Hex Key, release the flange
bolt and outer blade flange and the blade (if
fitted) from the arbor. (Fig. 28)
Note: The arbor screw has a LH (left hand)thread.
Turn clockwise to loosen.
Turn counterclockwise to tighten.
Ensure that the blade and blade flanges are clean
and free from any contamination.
