ASG BTL-20 Instruction Manual

Features and Benefits
• Starting Mode Adjustable: The ASG BTL-20 and BTL-30
can switch starting mode between Lever Start and
Push-to-Start. This design increases the flexibility on
the use of the ASG BTL series electric screwdrivers
and makes them suitable for every kind of working
environment.
• RPM Adjustable, Full Torque Output under Low RPM:
The BTL-20 and BTL-30 are speed adjustable electric
screwdrivers. The RPM is stepless and adjustable
between 100 RPM and 950 RPM to meet the working
requirements. The BTL-20 and BTL-30 provide full torque
output even under low RPM operation. Please note that
when operating under 300 RPM, the max torque output
of the BTL-30 will be less than 2 N.m (17.7 lbf.in).
• Ground Impedance of Bits < 1.0Ω: Accurate
electronics assembly requires extremely high
ESD protection. The ASG BTL series mini electric
screwdrivers adopt the unique interior ring grounding
approach, which enable the contact area of rotary
shaft of the bits and grounding end constantly remains
290mm 2 . Therefore, with the special designed
structure, the BTL-20 and BTL-30 screwdrivers can
remain their grounding impedance of bits < 1.0Ω for
long period of operation (about 5000 hours).
• Compatible with Screw Counter: ASG BTL-20
and BTL-30 brushless electric screwdrivers are only
compatible with the ASG BTL-5A switching power
supply. WIth the BTL-5A, the BTL-20 and BTL-30 are
also compatible with the STC-02 screw counter.
ASG STC-02 (ASG #65646)
• Stable and accurate torque output
• Low failure rate
