Warning

1. Read and understand the entire owner's manual before attempting assembly or operation.

2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with

all of these warnings may cause serious injury.

3. Replace the warning labels if they become obscured or removed.

4. This mortiser is designed and intended for use by properly trained and experienced personnel only. If

you are not familiar with the proper and safe operation of a mortiser, do not use until proper training and knowledge have been obtained.

5. Do not use this mortiser for other than its intended use. If used for other purposes, WMH Tool Group

disclaims any real or implied warranty and holds itself harmless from any injury that may result from that use.

6. Always wear approved safety glasses/face shields while using this mortiser. Everyday eyeglasses

only have impact resistant lenses; they are not safety glasses.

7. Before operating this mortiser, remove tie, rings, watches and other jewelry, and roll sleeves up past

the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are recommended. Do not wear gloves.

8. Wear ear protectors (plugs or muffs) during extended periods of operation.

9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities

contain chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead based paint.

• Crystalline silica from bricks, cement and other masonry products.

• Arsenic and chromium from chemically treated lumber.

Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area and work with approved safety equipment, such as face or dust masks that are specifically designed to filter out microscopic particles.

10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.

11. Make certain the machine is properly grounded.

12. Make all machine adjustments or maintenance with the machine unplugged from the power source.

13. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting

wrenches are removed from the machine before turning it on.

14. Keep safety guards in place at all times when the machine is in use. If removed for maintenance

purposes, use extreme caution and replace the guards immediately.

15. Check damaged parts. Before further use of the machine, a guard or other part that is damaged

should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

16. Provide for adequate space surrounding work area and non-glare, overhead lighting.

17. Keep the floor around the machine clean and free of scrap material, oil and grease.

18. Keep visitors a safe distance from the work area. Keep children away.

19. Make your workshop child proof with padlocks, master switches or by removing starter keys.

20. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are

careless acts that can result in serious injury.

21. Maintain a balanced stance at all times so that you do not fall or lean against the auger and chisel or

other moving parts. Do not overreach or use excessive force to perform any machine operation.

22. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for

which it was not designed. The right tool will do the job better and safer.

23. Use recommended accessories; improper accessories may be hazardous.

24. Maintain tools with care. Keep augers and chisels sharp and clean for the best and safest

performance. Follow instructions for lubricating and changing accessories.

25. Make sure the work piece is securely clamped against table and/or fence. Never use your hand to

hold the work piece.

26. Do not turn on the power while the auger or chisel is contacting a workpiece.

27. Turn off the machine before cleaning. Use a brush or compressed air to remove chips or debris — do

not use your hands.

28. Do not stand on the machine. Serious injury could occur if the machine tips over.

29. Never leave the machine running unattended. Turn the power off and do not leave the mortiser until

the auger comes to a complete stop.

30. Remove loose items and unnecessary work pieces from the area before starting the machine.

This means that if precautions are not heeded, it may result in serious injury or possibly

even death.

Assembly

Tools required for assembly

forklift or hoist with straps/slings 14mm wrench (provided) 4 and 6mm hex wrenches (provided)

1. Remove the four screws that secure the Mortiser to the wood pallet, using a 14mm wrench.

2. With a forklift or hoist, lift the machine off the pallet and into its desired location.

3. The Mortiser should be located in a dry area, on a sturdy, level floor, and with sufficient lighting. Leave plenty of space around the machine for operations and routine maintenance work.

4. If desired, the Mortiser can be further stabilized by securing it to the floor, using lag screws through the four holes in the base.

The mortiser should be

disconnected from the power source during assembly procedures.

5. Unpainted areas of the machine have been treated with a rust preventative. This should be removed with a soft cloth and a mild solvent. Do not use paint thinner, lacquer thinner, gasoline or mineral spirits; these will damage painted surfaces and plastic parts. Do not use an abrasive pad.

Installing Handle

1. Use a 4mm hex wrench to remove the screw, washer and spring from the shaft (Figure 1).

2. Mount the hub of the handle onto the shaft as shown. Make sure the hub slides all the way onto the shaft.

3. Re-install spring, washer and screw. Tighten screw.

Installing Wood Table
