OPERATIONAL CAUTIONS
Resting the unit after continuous work After use for continuous work, rest the unit for 15 minutes or so when replacing the battery. The temperature of the motor, switch, etc., will rise if the work is started again immediately after battery replacement, eventually resulting in burnout.

MAINTENANCE AND INSPECTION

WARNING
Be sure to turn oﬀ the switch and pull out the battery before doing any inspection or maintenance.

Inspecting the bit
Continued use of a dull or damaged bit will result in reduced cutting eﬃ ciency and may cause overloading of the motor. Replace the bit with a new one as soon as excessive abrasion is noted.
CAUTION
If a dull bit is used, reactive force is increased during the cutting operation. Avoid the use of the dull bit without repair.
Inspecting the screws
Regularly inspect all screws and ensure that they are fully tightened. Should any of the screws be loosened, retighten them immediately.
WARNING
Using this power tool with loosened screws is extremely dangerous.
Maintenance of the motor
The motor unit winding is the very “heart” of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
Check for Dust
WARNING
To prevent dust inhalation or eye irritation, wear protective safety goggles and a dust mask when using an air gun to clean.
Use an air gun or other similar tool to remove materials, chips, etc. which have adhered to the body (especially where indicated in Fig. 15), and wipe with a soft dry cloth or a cloth moistened with soapy water.
Do not use bleach, chlorine, gasoline, or thinner, for they may damage the plastics. (Fig. 15)
Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not been collected on the terminals.
On occasion check prior, during, and after the operation.
CAUTION
Remove any swarf or dust which may have collected on the terminals.
Failure to do so may result in malfunction.
Disposal of the exhausted battery
WARNING
Do not dispose of the exhausted battery. The battery must explode if it is incinerated. The battery is recyclable. At the end of its useful life, under various state and local laws, it may be illegal to dispose of this battery in the municipal waste stream. Check with your local solid waste oﬃ cials for details in your area for recycling options or proper disposal.
Storage
Storing in a place below 104°F (40°C) and out of the reach of children.
NOTE
Storing lithium-ion batteries Make sure the lithium-ion batteries have been fully charged before storing them.
Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, signiﬁ cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, signiﬁ cantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to ﬁ ve times.
If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.
Service and repairs
All quality power tools will eventually require servicing or replacement of parts because of wear from normal use. To assure that only authorized replacement parts will be used, all service and repairs must be performed by a Metabo HPT AUTHORIZED SERVICE CENTER, ONLY.
CAUTION In the operation and maintenance of power tools, the safety regulations, and standards prescribed in each country must be observed.
