Maintenance And Inspection - Metabo HPT C 8FSHE Instrucciones De Seguridad Y Manual De Instrucciones

TRANSPORTATION OF THE MAIN BODY
The vice assembly could be dropped during transportation. Either remove the
assembly or slip a piece of wood between the vice to fi rmly secure it.
Drop the head and insert the locking pin (see P. 10 "Releasing the locking pin").
Turn and loosen the side handle, turn the turntable as far right as it will go, and
secure the turntable by turning the handle to the fi xed position. This will make
the main body even more compact.
When transporting the main body, carry it in your arms, holding the grip located
on the base with both hands or carry handle.

MAINTENANCE AND INSPECTION

WARNING:
To avoid an accident or personal injury, always confi rm that the trigger switch is
turned OFF and the power plug has been disconnected from the receptacle before
performing any maintenance or inspection of this tool.
1. Inspecting the saw blade
Always replace the saw blade immediately upon the fi rst sign of deterioration or damage.
A damaged saw blade can cause personal injury and a worn saw blade can cause ineff ective operation and
possible overload to the motor.
CAUTION:
Never use a dull saw blade. When a saw blade is dull, its resistance to the hand
pressure applied by the tool handle tends to increase, making it unsafe to operate
the power tool.
2. Inspecting the carbon brushes (Fig. 49 and Fig. 50)
The carbon brushes in the motor are expendable parts.
If the carbon brushes become excessively worn, motor trouble might occur.
Therefore, inspect the carbon brushes periodically and replace them when they have become worn to the
wear limit line as shown in Fig. 49.
Also, keep the carbon brushes clean so that they will slide smoothly within the brush holders.
The carbon brushes can easily be removed after removal of the brush caps (see Fig. 50) with a slotted (minus)
screwdriver.

3. About Handling the Motor (see Fig. 1)
Winding of the motor is said to be the heart of this tool. Exercise utmost caution not to damage the winding by
exposing it to wash 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 eff ective to discharge dust and the like.
4. Inspecting the screws
Regularly inspect each component of the power tool for looseness.
Re-tighten screws on any loose part.
WARNING:
To prevent personal injury, never operate the power tool if any components are
loose.
5. Inspecting the lower guard for proper operation
Before each use of the tool, test the lower guard (see Fig. 8) to assure that it is in good condition and that it
moves smoothly.
Never use the tool unless the lower guard operates properly and it is in good mechanical condition.
