SAFETY

1.1. ELECTRICAL SAFETY
WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:  You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any other connectors for wear or damage. You must ensure that the risk of electric shock is minimized by the installation of appropriate safety devices. A Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a Residual Current Device (RCD) is used. It is particularly important to use an RCD with portable products that are plugged into a supply that is not protected by an RCCB. If in any doubt consult a qualified electrician. You may obtain a Residual Current Device by contacting your Sealey stockist.
You must also read and understand the following instructions concerning electrical safety. The Electricity at Work Act 1989 requires that all portable electrical appliances, if used on business premises, are tested by a qualified electrician, using a Portable Appliance Tester (PAT), at least once a year. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances and the safety of the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.

ASSEMBLY

‰ WARNING! DO NOT plug the mortises into the mains power supply until completely assembled and these instructions tell you to do so.
x DO NOT allow brake fluids, petroleum, penetrating oils etc. to come into contact with plastic parts of mortiser as damage may result.
WARNING! The mortiser is delivered with the head positioned low down on the two pillars and is held in this position by a  piece of wood inserted between the top of the head and the crosspiece on top of the pillars. Care must be taken when removing this piece of wood as the head is held under spring pressure and will move rapidly to the top of the pillars when the wood is removed.
4.1.RELEASING THE HEAD & HANDLE ASSY. Place the mortiser onto a firm, solid workbench and bring the cast base near to the front edge of the work surface. Assemble handle sleeve (fig.2.A) to pinion shaft (fig.2.B) using the spring and screw arrangement (fig.2.C, fig.2.D). Insert the threaded end of the handle (fig.1.D) through the hole in the sleeve (fig.2.A) on the side of the head and fix in place using the washers, spring and nut arrangement (fig.2.F). Steady the mortises by placing your left hand on top of the unit. Rotate the handle so that it is pointing downwards at 45°. Push the handle further down a small amount to take the pressure off the wood and get  a second person to remove the piece of wood. Slowly allow the handle to rotate upwards allowing the head to move to the top of the pillars in a controlled fashion.
4.2. WORK TABLE. (fig.1.F) Attach the Work Table to the cast base using the two countersunk M8 x 25mm Table fixing screws.
4.3. BACKSTOP ASSEMBLY & CLAMP (fig.1.H, fig.1.G, fig.3)

4.3.1. Insert fence bar (fig.3.B) to the hole (fig.3.C) and fasten by the handle (fig.3.A)
4.3.2. Insert the clamp (fig.3.E, fig.1.G) into the hold-down bar and fasten by handle (D)
4.3.3. Fasten the clamp assembly (fig.3.D, fig.3.E, fig.3.F) into the hole by screw (fig.3.G).
4.4. TOOL AND CHISEL HOLDER
4.4.1. Assemble tool and chisel holder (fig.1.A) to side of column using two screws supplied.

 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 the backstop to the desired position and tightening the 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 the screw knob (fig.6.C) and lower the head until the chisel is at the desired depth. Lower depth stop guide (A) until it is at the desired depth, and tighten the screw knob (fig.6. C).
5.4. INSTALLING CHISEL AND BIT
‰ WARNING! Ensure the mortiser is switched off and is unplugged from the main 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.

MAINTENANCE

WARNING! Ensure the mortiser is switched off and is unplugged from the mains power supply before carrying out any maintenance.
6.1. Clean and dust the mortiser, removing all waste materials.
6.2. Periodically apply a light coat of wax to base work surface which will help keep it clean and rust free.
6.3. Open shaft cover and apply a thin coat of light machine oil to drill bit shaft where it passes through the chisel, but not on the cutting edge.
Also lightly oil rack and pinion gear teeth upon which the main column moves up and down.
