Periodic inspections

Periodically check the following points.
Inspection
site
Robotic Mower Is there any abnormality with the mower blades? If mowing cannot be performed well, turn off the power switch, check the mower
Is the Robotic Mower traveling stable?
Is abnormal sound produced?
Can docking be performed correctly?
Charging Is the station indicator lighted green?
station
Is the charging station properly fixed?
Has foreign matter adhered to the terminals?
Is the guide wire protruding from the station
base?
AC adapter Are the power plug and connection terminals
and cabtire inserted firmly all the way?
cable
Are the cables damaged?
Work location Are any foreign objects present?
Is there any change in the work environment?
Is there any abnormality with the boundary wire
and guide wire installation?
Check item
blades for wear, cracks, or chips, and replace the mower blades if necessary.
If the Robotic Mower travels unstable, turn off the power switch and check if there
is any damage to the wheels and axles or if any foreign objects are caught or
rubbish and dirt has accumulated on the wheels and axles. If the problem is not
resolved, contact our sales office.
If abnormal sound is produced, turn off the power switch and check if there are any
foreign objects caught in the rotating parts of the wheels and the mower blades. If
the problem is not resolved, contact our sales office.
If docking cannot be performed, turn off the power switch, move the Robotic
Mower by hand, and check whether proper docking with the charging station is
possible. If proper docking is not possible, check the following points.
- Remove any obstacles from near the wheels.
- Attach the top cover correctly. (The top cover should be fixed in three places)
- If the ground under the station base is uneven, smooth it.
If it is lighted or blinking red or off, the Robotic Mower will be unable to execute
mowing. Check the following points and take the appropriate countermeasures.
- Is the AC adapter connected properly to a power outlet?
- Is the cabtire cable connected properly to the AC adapter and the charging
station?
- Are the boundary wire connectors connected properly to the charging station?
- Are couplers attached on the boundary wire connected properly?
- Is the boundary wire broken partway?
If the charging station moves, retighten the screw pegs with the hex wrench 6.
Some adhered matter may hinder proper communication and charging. Clean
away any dirt on the charging terminal and other terminals.
If the guide wire protrudes from the groove of the station base, insert it again.
If a power outlet or connection terminal insertion is loose, insert it again.
If a cable sheath is peeled or severely damaged, contact our sales office.
Clear away any objects that may damage the mower blades or get caught in the
rotating parts of the Robotic Mower. (Small stones, sticks, rubbish, string-like
objects, etc.)
Take the following countermeasures.
- If the grass height exceeds 100 mm, cut it down to that height or less.
- Clear away any weeds that are higher than the lawn.
- Fill in any holes or depressions and smooth out local unevenness.
- Refrain from use if there are deep puddles or snow accumulation.
If the wires float from the ground, fix them again with the pegs.
