5 Repair instructions

All repairs to robotic lawnmowers should be done indoors
on a clean work bench to protect sensitive components
from moisture and dirt.
All screws in the robotic lawnmower must be fitted using the
correct tightening torque according to the values in Table 3:
Screw fasteners on page 79.
The repair instructions shows a Husqvarna Automower®
315, but are relevant also for 310 and GARDENA R100Li,
R100LiC,R130Li, R130LiC, R160Li.
IMPORTANT INFORMATION
Oil, grease and dirt on electrical connections
can cause intermittent faults on the robotic
lawnmower. These faults only occur
at times, which make them difficult to
find. Never touch sensitive electronic
components with your fingers, for example,
connectors or components on a circuit
board.
To avoid electrostatic discharge in
electronic components always earth
yourself, for example against a radiator,
before you start to work on electrical
components.
Always disconnect cables from a component
by pulling the connector. Do not pull the
actual cable.
Never use any form of silicone or the like
when repairing a robotic lawnmower.
If possible test that components work
before completely assembling the robotic
lawnmower.
Always set the main switch to position 0
before connecting or disconnecting any
cables to connectors (e.g. the HMI cable to
the main circuit board). If the main switch
is left in position 1, the circuit board may
be destroyed when cables are connected.
