WARNING
● Be sure to turn off the switch and pull out the
battery before doing any inspection or
maintenance.
● Before storing the tool body, throw away the
chips in the dust box, and clean the inside of the
dust box and storage case. Also, attach the
battery cover to the battery when removing and
storing it.
1. Inspecting the saw blade
Continued use of a dull or damaged blade will result
in reduced cutting efficiency and may cause
overloading of the motor. Replace the blade with a
new one as soon as excessive abrasion is noted.
WARNING
If a dull saw blade is used, reactive force is
increased during cutting operation. Avoid using
a dull saw blade.
2. Check the Screws
Loose screws are dangerous. Regularly inspect them
and make sure they are tight.
CAUTION
Using this power tool with loosened screws is
extremely dangerous.
3. Motor unit maintenance
The motor winding is an important part of this tool.
Avoid damaging and be careful to avoid contact with
cleaning oil or water.
NOTE
Accumulation of dust and the like inside the motor
can result in a malfunction.
After using the motor for 50 hours or so, carry out no-
load running, and blow in the dry air from a wind hole
at the motor's rear. Such action is effective to
discharge dust and the like.
4. Inspecting and maintaining the lower guard
Always make sure that the lower guard moves
smoothly.
In the event of any malfunction, immediately repair
the lower guard.
5. Inspection of terminals (Tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.

MAINTENANCE AND INSPECTION
CAUTION
Remove any swarf or dust which may have
collected on the terminals.
Failure to do so may result in malfunction.
6. Check for dust
Dust may be removed with a soft cloth or a cloth
dampened with soapy water.
Do not use bleach, chlorine, gasoline or thinner, for
they may damage the plastics.
7. Disposal of the exhausted battery
WARNING
Do not dispose of the exhausted battery. The
battery may explode if it is incinerated. The
battery is recyclable. At the end of it's useful life,
under various state and local laws, it may be
illegal to dispose of this battery into the
municipal waste stream. Check with your local
solid waste officials for details in your area for
recycling options or proper disposal.
8. Storage
Store the power tool and the battery in a place in
which the temperature is less than 104°F (40°C) and
out of 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, significantly reducing battery usage
time or rendering the batteries incapable of holding a
charge.
However, significantly reduced battery usage time
may be recovered by repeatedly charging and using
the batteries two to five times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries
dead and purchase new batteries.
9. 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.
