ELECTRICAL SAFETY
CAUTION: How to avoid accidents and
injuries from electric shock:
• Do not use the device if the switch cannot be
switched on and off. Have a defective switch
replaced.
• Do not carry the device by the cable. Do not
unplug from the socket by the cable. Protect
the cable from heat, oil and sharp edges.
• Operate only from a rated voltage of 12 volts
(direct voltage). Higher voltage ratings will
destroy the compressor.
• Make sure there is reliable contact between the
socket-outlet and the plug. Poor contact will
lead to overheating and risk of fire.
• Only connect the connection cable to the ciga-
rette lighter socket in the car.
• Follow the instructions of your automaker on
using the cigarette lighter socket.
• If the cable is damaged, immediately unplug
from the cigarette lighter socket.
• The connection cable on this device cannot be
replaced.
• Dispose of the device if the cable is damaged.
2. MACHINE INFORMATION
Intended use
The device is intended to produce pressure in tyres
(e.g. car and motorcycle tyres), balls, air mattresses
and other small inflatable products. The car compres-
sor is operated via a 12V cigarette lighter socket (car,
mobile home, truck etc.).This device is not suitable for
continuous operation to produce pressure over 3 bar.
Any other use may damage the device and present a
serious danger to the user. The manufacturer is not li-
able for damage caused by improper use or incorrect
operation. This device is not suitable for commercial
use. Commercial use will void the warranty.

3. OPERATION
First use
Fig. A
Place the product on a level, non-flammable sur-
face. Depending on the inflatable you can use the
connection valve (7) directly or along with one of
the included valve adapters (8, 9, 10).
For inflatables with counterpressure (e.g. partly
filled car tyre): Switch on the product before con-
necting the connection valve (7) to the tyre.
This product is not suitable for continuous oper-
ation. It was developed to produce air pressure,
not air volume. Do not use the product for longer
than 10 minutes without interruption to prevent
CR502DC
overheating and damage to the device. Afterwards
12V
allow to cool for a minimum of 10 minutes.

Do not cover the vents.
Do not operate the device in dusty
environments. Doing so poses a fire hazard
and could damage the device.
