2.6 Use according to intended purpose

The MAFELL portable electric plane MHU 82 is intended exclusively for cutting operations on solid timber and sheet materials, such as particle board, core-boards and MDF boards, using TCT knives. The dimension of the clamping devices, knife supports and the knives used must correspond to the Ref. Nos in the spare parts list. Any other use beyond this scope is considered as failing to comply with the intended purpose. The manufacturer is not liable for any damage caused as a result of this; the risk is borne solely by the user. The machine is not suitable for operation in the rain outdoors or in areas subject to explosion hazards. Use according to the intended purpose also includes compliance with the operating, maintenance and repair conditions specified by the manufacturer, and adherence to the safety instructions contained in the operating manual. The portable electric plane MHU 82 must be operated, tooled and maintained only by persons familiar with the machines and instructed as to the risks. Repair work must be carried out by MAFELL authorized dealers or MAFELL customer service agencies. The relevant accident prevention regulations and other generally recognized industrial, medical and technical safety rules must be complied with. Unauthorized modifications to the machine preclude the liability of the manufacturer for any resultant damage.

Danger Even if used in accordance with its intended purpose and despite conforming with the safety instructions, residual risks caused by the intended use that can lead to health consequences will always remain. - Touching the running planing shaft below the base plate. - Touching the sharp planing blades with stationary planing shaft. - Touching the sharp planing blade edges when changing the blades. - Touching the running planing shaft through the chip ejector. - Ejection of incorrectly fitted planing blades. - Breakage and ejection of parts of the planing blades. - Machine or workpiece get flung off when planing from within the workpiece. - Touching live parts with the housing open and the mains plug not removed. - Hearing can be impaired when working for long periods without ear protectors. - Emission of harmful wood dusts during longer operation without extraction. 3 Safety instructions Danger Always observe the following safety instructions and the safety regulations applicable in the respective country of use! General instructions: - Children and adolescents must not operate this machine. This rule does not apply to young persons receiving training and being supervised by an expert. - Never work without the protection devices prescribed for the respective operating sequence and do not make any changes to the machine that could impair safety. - When operating the machine outdoors, use of an earth-leakage circuit-breaker is recommended. - Damaged cables or plugs must be immediately replaced. Replacement may only be carried out by Mafell or an authorised MAFELL service workshop in order to avoid safety hazards. - Always check before beginning work whether the protection and work devices are safely attached and not damaged. Damaged protection devices and parts must be repaired or exchanged appropriately. - Consider environmental influences. Do not expose the machine to rain and avoid working in a damp or wet environment as well as near to combustible liquids and gases.-16- - Do not carry the machine by its cable and do not use the cable to pull the plug out of the socket outlet. - Pay attention that the cable is protected against oil and heat and is not pulled across sharp edges. - Avoid sharp bends in the cable. Especially when transporting and storing the machine, do not wind the cable around the machine. - Only allow an electrician to carry out work on the electrical parts of the machine. - Store the machine in a dry, locked place outside the reach of children. Instructions on the use of personal protective equipment: - Always wear ear protectors during work. - Always where a dust mark during work. Instructions on operation: - Wait for the cutter top stop before setting the tool down. An exposed rotating cutter may engage the surface leading to possible loss of control and serious injury. - Hold the power tool by insulated gripping surfaces, because the cutter may contact its own cord. Cutting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock. - Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the workpiece by your hand or against the body leaves it unstable and may lead to loss of control. - Provide for an unobstructed and slip-proof location with adequate lighting. - The power plug must be pulled before replacing tools, making adjustments and repairing malfunctions (this also comprises removing jammed chips). - Do not work on workpieces which are too small or too large for the capability of the machine. - The switch may not be wedged. - Only begin planing the workpiece when the planing shaft has achieved its full speed. - Examine the workpiece for foreign objects. Never attempt to plane over nails or other metal objects. - During planing, always lead the connecting cable away from the machine to the side. - An even feed during planing increases the life time of blades and machine and reduces the risk of accidents. Do not reverse plane or plunge plane! - Planing blades must be reversed or replaced in good time, as blunt blades do not only increase the danger of backlash, but also place an unnecessary strain on the motor. - Never reach into the planing shaft or into the chip ejector while the machine is running. - The wood dust arising during planing impairs the necessary view and is partly injurious to health. If the machine is used for longer periods, it must therefore be connected to a chip extractor, e.g. a portable small extractor, if the work is not carried out outdoors or in a sufficiently ventilated room. The air velocity must be at least 20 m/s (65.6 ft/sec.). Instructions on service and maintenance: - Regularly cleaning the machine, especially the adjusting devices and guides, constitutes an important safety factor. - Only original MAFELL spare parts and accessories may be used. Otherwise the manufacturer will not accept any warranty claims and cannot be held liable. - Use a suitable tool, e.g. a piece of wood to clean a clogged ejection nozzle. Do not reach into the ejection nozzle. 4 Setting / Adjustment

4.1 Mains connection

The portable electric plane MHU 82 has Class II protective insulation (double-insulated). Prior to commissioning make sure that the mains voltage complies with the operating voltage stated on the machine's rating plate.

When machining wood for a long period and when using the machine industrially with materials that generate dust which represents a health hazard, the machine must be connected to a suitable dust extractor unit.-17- Note: German TRGS 553 «wood dust» requires the use of tested extraction devices. When using other equipment, industrial users must ascertain any special requirements by consulting the relevant liability insurance association. The portable electric plane will remain within thetechnical guideline value for wood dust concentration(2 mg/m³) only if connected to a tested extractor unit.

4.3 Mounting of the hose connector

Enclosed screws with spacer sleeves are to be screwed into the housing below the connecting piece of the chip ejector. Attach hose connector until snap- on cap locks.

4.4 Change and adjustment of knives

Danger Pull the power plug during all service work. Loosen pressure screws 17, remove knife 19 laterally, turn it over, insert it again and align it laterally with front and rear support. Tighten pressure screws (8.4 Nm). When using a one-hand planer, make sure that the position of the cutters and clamping jaws matches, as this ensures a perfect planing pattern. The height of the planing cutters can be adjusted with the adjusting screws 18. The cutter head, clamping devices, knife supports and knives have to be cleaned when turning or exchanging them – see paragraph 6. (Maintenance). 5 Operation

5.1 Switching on and off

To switch on the machine, hold down the starting lock- off button 3 and press switch 2. Since this is not a latching switch, the motor runs only as long as the switch is pressed down. To switch off, release switch 2. The starting lock-off button prevent the machine from being switched on accidentally.

Danger Before switching on, pay attention that the machine's planing shaft does not rest on the support or on the workpiece.

5.2 Adjusting cutting depth

Turn button for adjusting cutting depth 4 to cutting depth desired according to scale 21.

5.3 Operation instructions

The plane can be guided well with handle 1. Please pay attention that the front support of the plane rests well on the wood. 6 Maintenance

Danger Pull the power plug during all service work. MAFELL machines are designed to be low in maintenance. The ball bearings used are greased for life. When the machine has been in operation for a longer period of time, we recommend to hand the machine in at an authorised MAFELL customer service shop for inspection. The machine must be regularly cleaned of dust, at the same time blowing out the motor ventilation apertures. The cutter head, clamping devices, knife supports and knives used on the machine must be freed from resin regularly as a clean tool improves the cutting quality. This can be done by soaking the clamping devices, knife supports and knives for 24 hours in paraffin, white spirit or commercially available resin remover.

Aluminium tools may only be deresinified with solvents which do not corrode the aluminium.-18- 7 Troubleshooting

Danger Determining the causes for existing defects and eliminating these always requires increased attention and caution. Pull the mains plug beforehand! Some of the most frequent defects and their causes are listed in the following chart. In case of other defects, contact your dealer or the Mafell customer service. Defect Cause Elimination Machine cannot be switched on No mains voltage Check power supply Carbon brushes worn Take the machine to a MAFELL customer service agency Machine switches itself off when idling or while cutting is in progress Mains failure Check mains backup fuse Unsatisfactory finish Blunt knives Reverse or replace knives Uneven feed Cut with constant pressure and reduced feedrate Chip ejection blocked Wood is too damp

Extended operation without extraction Connect to an external extractor, e.g. portable dust extractor 8 Optional accessories
