5. Confirm the position of the spindle lock before using
the tool.
After installing the saw blade, confirm that the spindle
lock has been returned to the released position before
using the power tool (see Fig. 4).
6. Eye protection
WARNING
Operating the tool without wearing proper eye
protection may result in serious injury.
Always wear eye protection with side shields that meets
the requirements of ANSI Standard Z87.1.
Ordinary eyeglasses do not provide adequate protection
because they do not contain impact resistant safety glass.
AFTER INSTALLING THE POWER SUPPLY
(BATTERY) TO THE TOOL, CHECK THE OPERATION
OF THE TOOL AS FOLLOWS:
7. Electric brake
WARNING
Please be aware of the reaction of the Motor
Head (Fig. 3) when the brake is activated.
Braking causes the Motor Head to jerk downward
and the user should be prepared for this
reaction, especially when the trigger switch is
released before the blade is completely down.
Failure to be familiar with, and prepared for, the
operational characteristics of the tool may cause
serious injury.
This tool is equipped with an electric brake which will
typically stop the blade within 5 seconds after the trigger
switch is released.

Occasionally, there will be a delay in the brake engaging
which will result in a longer blade stopping time. On rare
occasions, the brake may not engage at all and the saw
blade will coast to a stop.
If the brake fails to engage frequently, depress and
release the trigger switch to turn the tool on and off 4 or
5 times. If the brake still does not engage, have the tool
serviced at a metabo HPT authorized service center.
The brake is not a substitute for a properly functioning
lower guard. Check the function of the lower guard before
each use. Serious personal injury may occur if the lower
guard does not move smoothly and cover the blade
properly.
8. Trial Run
After confirming that no one is standing behind, the
power tool start and confirm that no operating
abnormalities exist before attempting a cutting
operation.
9. Inspect the rotating stability of the saw blade.
For precise cutting, rotate the saw blade and check
for deflection to confirm that the blade is not
noticeably unstable; otherwise vibrations might occur
and cause an accident.
BEFORE CUTTING
1. Positioning the table insert
Table inserts are installed on the turntable. When
shipping the tool from the factory, the table inserts are
so fixed that the saw blade does not contact them.
The burr of the bottom surface of the workpiece is
remarkably reduced, if the table insert is fixed so that
the gap between the side surface of the table insert
and the saw blade will be minimum. Before using the
tool, eliminate this gap in accordance with the
following procedure.
(1) Right angle cutting
Loosen the three 5 mm machine screws, then secure
the left side table insert and temporarily tighten the
5 mm machine screws of both ends. Then fix a
workpiece (about 7-7/8" (200 mm) wide) with the vise
assembly and cut it off. After aligning the cutting
surface with the edge of the table insert, securely
tighten the 5 mm machine screws of both ends.
Remove the workpiece and securely tighten the 5 mm
center machine screw. Adjust the right hand table
insert in the same way. (Fig. 17-a)
