• In some instances, objects passing between the machine and transmitter
(such as support beams) will block the signal. When this occurs, the ma-
chine will stop moving. If the signal is not re-established within 30 sec-
onds, the engine will shut down.
• In an enclosed area (such as a shop floor or warehouse) or an area sur-
rounded by large structures, the infrared signal may reflect off surround-
ing surfaces, causing it to be picked up by the machine even when the
transmitter is pointed away from the machine. This condition is more pro-
nounced at shorter distances when the signal strength is strong.
• As the distance between the transmitter and machine increases, the in-
tensity of the signal diminishes.
6.15 Communication Faults
Description
The decoder has built-in diagnostics that continuously check for a faulty sig-
nal transmitted from the receiving eyes to the decoder. If a faulty signal is
detected, the decoder stops machine movement and the light rings illumi-
nate solid amber.
Fault correction
Communication faults may occur when a receiving eye is damaged. The
faults vary in frequency and duration. When a normal signal is restored, the
light rings slowly flash amber and machine movement is restored.
If communication faults occur regularly, check the condition of the receiving
eyes. Replace damaged components as needed.
6.16 Preliminary Checks
NOTICE
Contaminated oil can cause machine damage.
► When topping off the lubricating and hydraulic oil levels, use clean con-
tainers, funnels, etc., to avoid contamination. For further information,
Engine Maintenance—Honda GX630 (Gasoline), Engine Maintenance—
Kubota D902 (Diesel), or Engine Maintenance—Kohler ECH630 (Gaso-
line).
Requirement
Machine on level surface
Before starting
Check the following items:
• Engine coolant level (diesel only)
• Engine oil level
• Hydraulic oil level
