TOOL AND CHISEL HOLDER
4.4.1.
Assemble tool and chisel holder (fig.1.A) to side of column using two screws supplied.
5. OPERATION
5.1.
RAISING AND LOWERING THE HEAD
The head (fig.4.A) is raised and lowered by means of the lever (fig.4.B). For maximum leverage during the mortising operation, the lever
(fig.4.B) can be repositioned by pulling out the hub (fig.4.C) of the lever assembly and repositioning hub on the pinion shaft.
5.2.
ADJUSTING THE FENCE
The backstop (fig.5.A) can be moved in or out by loosening lever (fig.5.B), slide backstop to desired position and tighten lever (fig.5.B).
NOTE:
Lever (fig.5.B) is spring-loaded and can be repositioned by pulling out on the lever and repositioning it on the serrated nut located
underneath the lever.
5.3.
DEPTH STOP
A depth stop guide (fig.6.A) is provided to limit the depth of the chisel. To adjust the depth stop guide (fig.6.A), loosen screw
knob (fig.6.C) and lower head until the chisel is at the desired depth. Lower depth stop guide (A) until it is at the desired depth, tighten
screw knob (fig.6. C).
5.4.
INSTALLING CHISEL AND BIT
WARNING!
Ensure the mortiser is switched off and is unplugged from the mains power supply.
WARNING!
Use gloves when handling drill and chisel bits as the ends are very sharp.
NOTE:
Set the slot in the side of the chisel to the left or right, NOT to the front or back. This allows chips to escape when cutting mortises.
5.4.1.
Remove the access cover (fig.1.E) and loosen lock screw (fig.7).
5.4.2.
Insert chisel bushing (with the hole facing forward) into the head. Tighten the screw just enough to hold the chisel in place.
5.4.3.
Push the chisel up as far as possible into the head. Then lower the chisel approximately 0.8mm to 1.6mm, depending on the type of wood
being worked. Tighten the screw to hold chisel in place.
5.4.4.
Push bit up through the chisel opening as far as it will go. Lock the drill bit in place with the chuck key.
5.4.5.
Loosen lock screw and push chisel up against the bushing, then tighten screw. This should provide the proper distance between the
points of the chisel and the bit.
