MODE SELECTION BSS18SBL
Speed mode 1
Low Speed (1300 min
-1
)
Low torque (45 Nm)
Use this mode to drive small
fasteners when lowest speed and
force are required.
Speed mode 2
Medium speed (1950 min
-1
)
Medium torque (120 Nm)
Use this mode to drive medium-sized
fasteners when medium force and
speed are required.
Speed mode 3
Maximum speed (2900 min
-1
)
Maximum torque (200 Nm)
Use this mode to drive large
fasteners when maxmium force and
speed is required.
MODE SELECTION BSS18S12BL
Speed mode 1
Medium speed (1200 min
-1
)
Medium torque (100 Nm)
Use this mode to drive medium-sized
fasteners when medium torque is
required.
Speed mode 2
High Speed (2000 min
-1
)
High torque (220 Nm)
Use this mode to drive large
fasteners when high torque is
required.
Speed mode 3
Maximum speed (2800 min
-1
)
Maximum torque (280 Nm)
Use this mode to drive large
fasteners when maxmium force and
speed are required.
Mode A: Auto tight (90 Nm)
Use this mode to avoid overdriving
the nut or bolt. After the impact
wrench detects a resistance, it
impacts for about 1 second and then
stops automatically.
OPERATION
Note: It is recommended after fastening to always check
the torque with a torque wrench.
The fastening torque is a
ff
ected by a wide variety of factors
including the following.
• State of battery charge – When the battery is discharged
voltage will drop and the fastening torque will be reduced.
• Operation at speeds – Operating the tool at low speeds will
cause a reduction in fastening torques.
• Fastening position – Holding the tool or the driving fastener in
various angles will a
ff
ect the torque.
• Drive accessory/socket – Failure to use the correct size
accessory or socket, or a non-impact rated accessory may
cause a reduction in the fastening torque.
• Use of accessories and extensions – Depending on the
accessory or extension
fi
tment can reduce the fastening force
of the impact wrench.
• Bolt/Nut – Fastening torques may di
ff
er according to the
diameter of the nut or bolt, the class of nut/bolt and the length
of nut/bolt.
• Condition of the fastener – Contaminated, corroded, dry or
lubricated fasteners may vary the fastening torques.
• Condition and base material – The base material of the
fastener and any component in between the surfaces may
e
ff
ect the fastening torque (dry or lubricated base, soft or
hard base, disc, seal or washer between fastener and base
material).
IMPACTING TECHNIQUES
The longer a bolt, screw, or nut is impacted, the tighter it will
become.
To help prevent damaging the fasteners or workpieces, avoid
excessive impacting.
Be particularly careful when impacting smaller fasteners
because they require less impacting to reach optimum torque.
Practice with various fasteners, noting the length of time
required to reach the desired torque.
Check the tightness with a hand-torque wrench.
If the fasteners are too tight, reduce the impacting time.
If they are not tight enough, increase the impacting time.
Oil, dirt, rust or other matter on the threads or under the head
of the fastener a
ff
ects the degree of tightness.
The torque required to loosen a fastener averages 75% to 80%
of the tightening torque, depending on the condition of the
contacting surfaces.
On light gasket jobs, run each fastener down to a relatively light
torque and use a hand torque wrench for
fi
nal tightening.
BATTERIES
Battery packs which have not been used for some time should
be recharged before use.
Temperatures in excess of 50°C (122°F) reduce the
performance of the battery pack. Avoid extended exposure to
heat or sunshine (risk of overheating).
The contacts of chargers and battery packs must be kept clean.
For an optimum life-time, the battery packs have to be fully
charged, after used.
