4.1-3 Troubleshooting Chart
Determine All The Facts – It is important to gather all
the facts about the problem before beginning any service
procedures. The first step is to talk to the equipment
operator. Ask for a complete description of the malfunc-
tion. Guidelines below and on the following pages can
then be used as a starting point to begin troubleshooting.
Clamp Circuit
• Clamp drops load after it has been picked up.
• Clamp will not carry load up to its rated capacity.
• Clamp arms have uneven travel.
• Clamp arms travel slowly.
• Clamp arms will not move.
To correct these problems, see Sections 4.3-1
and 4.3-2.
NOTE: Some Clamps have a regenerative hydraulic
circuit that causes the arms to open at a faster speed
than when closing. This is a normal Clamp function.
Sideshift Circuit
• Clamp drops load while sideshifting.
• Clamp drops load at end of sideshift stroke.
• Clamp sideshifts left and right at different speeds.
• Clamp will not sideshift.
To correct these problems, see Sections 4.4-1
and 4.4-2.
Carton Clamp Loads
• Front stack of load tilts out.
• Lower tier of load bridges down or slides out.
• Lower tier of load is creased.
To correct these problems, see Section 4.1-4.
