Metabo PKU 250 Operating Instructions Manual page 6

Danger! Risk of electric shock!
• Do not expose tool to rain.
Do not operate tool in damp or wet environment.
• Prevent body contact with earthed objects such as radiators, pipes, cooking stoves,
refrigerators when operating this tool.
• Do not use the power cable for purposes it is not intended for.
Risk of personal injury and crushing by moving parts!
• Do not operate the tool without installed guards.
• Always keep sufficient distance to the saw blade. Use suitable feeding aids, if
necessary. Keep sufficient distance to driven components when the operating electric
tool.
• Wait for the saw blade to come to a complete stop before removing cutoffs, scrap,
etc. from the work area.
• Do not attempt to stop the saw blade by pushing the workpiece against its side.
• Ensure the tool is disconnected from power before servicing.
• Ensure that when switching on (e.g. after servicing) no tools or loose parts are left
on or in the tool.
• Turn power off if the tool is not used.
• Cutting hazard, even with the cutting tool at standstill!
• Wear gloves when changing cutting tools.
• Store saw blade in such manner that nobody will get hurt.
Risk of kickback
(workpiece is caught by the saw blade and thrown against the operator):
• Always work with a properly set riving knife.
• Do not jam workpieces.
• Make sure the saw blade is suitable for the workpiece material.
• Cut thin or thin-walled workpieces only with fine-toothed saw blades.
• Always use sharp saw blades.
• If in doubt, check workpiece for inclusion of foreign matter (e.g. nails or screws).
• Cut only stock of dimensions that allow for safe and secure holding while cutting.
• Never cut several workpieces at the same time – and also no bundles containing
several individual pieces. Risk of personal injury if individual pieces are caught by the
saw blade uncontrolled.
• Remove small cutoffs, scrap, etc. from the work area – when doing so the saw
blade must be at a complete standstill.
Drawing-in/trapping hazard!
• Ensure that no parts of the body or clothing can be caught and drawn in by rotating
components (no neckties, no gloves, no loose-fitting clothes; contain long hair with
hairnet).
• Never attempt to cut any workpieces which contain
- ropes,
- strings,
- cords,
- cables or
- wires, or to which any of the above are attached.
Hazard generated by insufficient personal protection gear!
• Wear hearing protection.
• Wear safety glasses.
• Wear dust mask.
• Wear suitable work clothes.
• When working outdoors wearing of non-slip shoes is recommended.
Risk of injury by inhaled wood dust
• Dust of certain timber species (e.g. beech, oak, ash) can cause cancer when
10
inhaled. Work only with a suitable dust collector attached to the saw. The dust
collector must comply with the data stated in the technical specifications.
The dust collector must meet the following requirements:
- suitable for the outer diameter of the suction ports (blade guard 35 mm; chipcase
80 mm);
- air flow volume ≥ 335 m
3 /h;
- vacuum at dust extraction port of saw ≥ 900 Pa;
- air speed at dust extraction port of saw ≥ 23,6 m/ s.
Ensure that as little as possible wood dust will get into the environment:
• remove wood dust deposit in the work area (do not blow away!);
• fix any leakages on the dust collector;
• ensure good ventilation.
Hazard generated by modification of the machine or use of parts not tested and
approved by the equipment manufacturer!
• Assemble tool in strict accordance with these instructions.
• Use only parts approved by the equipment manufacturer. This applies especially for:
- saw blades;
- safety devices.
• Do not change any parts.
Hazard generated by tool defects!
• Keep tool and accessories in good repair. Observe the maintenance instructions.
• Before every use check tool for possible damage: before operating the tool all safety
devices, protective guards or slightly damaged parts need to be checked for proper
function as specified. Check to see that all moving parts work properly and do not
jam. All parts must be correctly installed and meet all conditions necessary for the
proper operation of the tool.
• Damaged protection devices or parts must be repaired or replaced by a qualified
specialist. Have damaged switches replaced by a service centre. Do not operate tool
if the switch cannot be turned ON or OFF.
• Keep handles free of oil and grease.
Risk of injury by noise!
• Wear hearing protection.
• Make sure the riving knife is not bend. A bent riving knife will push the workpiece
against the side of the saw blade, causing noise.
Danger!
Before carrying out any fault service or maintenance work, always:
- switch machine OFF;
- unplug power cable;
- wait for saw blade to come to standstill.
Check that all safety devices are operational again after each fault service.
