Introduction
Visual Inspection
Hardware
Hardware needs to be verified that it is present and tight. Loose or missing hardware can cause severe
equipment damage and/or unsafe operational conditions.
Adjustments
1. Cushions - Most of Labrie’s arm cylinders are cushioned. These cushions provide a smooth stop at
the end of the cylinder stroke, reducing impact and noise, which helps in the comfort of the drivers.
An improperly cushioned cylinder will cause damage to both the arm and cylinder. For cushion
adjustment procedures, see Cylinder Cushion Adjustment on page 390.
2.
Proximity and Limit Switches
-
Proximity and limit switches are used to limit travel of moving parts
and/or to ensure conditions are safe for operation.
If these switches are not adjusted properly, damage to the equipment may occur as well as poor or
dangerous functionality.
For more information on proximity/limit switches, see
Proximity and Limit Switches on page 200.
General Wear and Damage
1. Leaks - Verify that they are not any leaking hydraulic cylinders, hoses, tubes, valves, or pumps.
Leaks in the hydraulic system are an indicator of possibly overheating hydraulics, damage to a seal,
over-pressurization, or general wear. To avoid costly and premature replacement of parts, ensure all
leaks are addressed properly and timely.
2.
Cracks - Ensure that they are not any cracks forming along the hopper floor edge, body, tailgate,
and/or arm/tipper/bucket if applicable. This is an indicator that something is worn, not adjusted
properly, or damaged.
3.
Bushings/Bearings/Slides - Check for play in any bushing, bearing, or slide. This may require the
use of a pry bar or lifting equipment. For example, the lift pivot bushing on the H
ELPING
-H
AND
™ will
need a forklift or lifting device to pick up on one side of the H
ELPING
-H
AND
™ gripper assembly. While
lifting, look for any movement of the pivot separated from the arm slide. This is an indicator that the
bushing is in need of replacement.
