Cleaning and maintaining
the HAWK Pen
CAUTION
Risk of short circuits and risk of mild
electric shocks
If components of the HAWK Pen are
dismantled and cleaned while still
powered, there is a risk of mild electric
shock and damage to the electronics in
the drive unit.
Before starting any cleaning and
maintenance
work,
the power supply to the HAWK Pen.
NOTICE
Damage to drive caused by fluid
If cleaning fluid or disinfectant gets
inside the drive, this can corrode the
electrical and mechanical components.
Never immerse the drive in cleaning
fluid or disinfectant.
Never use an autoclave or an
ultrasonic bath to clean the drive and
the connecting cable.

Pay attention to compatibility of
materials when selecting cleaning
agents
the following section
Accidental changes to the needle
depth due to greasing
If the grip or O-rings are greased, this
may cause the grip to become too
easy to turn. That in turn can cause the
needle depth to be altered accidentally.
Never apply grease to the grip or the
switch
off
O-rings.

Based on the following material com-
patibilities, you can assess which other
cleaning agents and disinfectants are
suitable.
The HAWK Pen's anodized aluminum
components resist:
• Weak acids (e.g. acetic acid ≤ 10%, citric
acid ≤ 10%)
• Aliphatic hydrocarbons (e.g. pentane,
hexane)
• Ethanol
• Most inorganic salts and their aqueous
solutions (e.g. sodium chloride, calcium
chloride, magnesium sulphate)
The components of the HAWK Pen are not
resistant to:
• Strong acids (e.g. hydrochloric acid,
sulphuric acid, nitric acid)
• Oxidising acids (e.g. peracetic acid)
• Lyes (e.g. caustic soda, ammonia and
all substances with a pH value > 7)
• Aromatic/halogenised
(e.g. phenol, chloroform) as well as
• acetone and benzene
hydrocarbons
