9.1.1 Maintenance Schedule Overview
In Table 9.1, the method described for daily
inspections is identified as a "walk around". All
external components must be looked at for any
visible signs of wear, damage, loose, missing or
unsecured fasteners, fluid leaks, and cracks in welds.
9.1.2 Conditional Maintenance
When properly installed, operated and maintained by
qualified personnel, the Allied equipment requires a
minimum of maintenance.
Table 9.1 specifies how often and what items need to
be inspected in order to maintain the safety, reliability
and performance of the Allied equipment. Intervals
are based on standard (normal) operating conditions
and must be adjusted accordingly if operating under
harsh applications or extreme conditions. For
example, if using water content hydraulic fluid or
when operating under conditions of extreme
temperatures, dust, high elevations, or extended
continuous use, components will require more
frequent monitoring. Use regular component
inspection to determine if interval adjustment is
warranted.
While the frequency of inspections and maintenance
depend primarily on use, other factors such as
extreme environmental conditions require additional
measures.
Clean the Surfaces of Ho-Pac

Muddy and wet soils.
If reduced performance is observed
9.2 Safety Precautions During Inspection
WARNING
Unless otherwise instructed, all
maintenance is performed with the work
tool supported on stable ground and the
machine shut off.
Remove the ignition key, engage interlock and apply
parking brake.
WARNING
Crush injury. Never rely on the rotation
system or cylinders as a means of
support when servicing the Allied
equipment. Hydraulic cylinders are
strictly lifting devices and not a
structural support member.
Prevent sudden or unexpected movement by using
proper blocking to support loads.
WARNING
Pressurized system. When releasing
pressure in the hydraulic system ensure
load cannot fall or make unexpected
movements.
Refer to the hydraulic maintenance section for
instructions on how to depressurize the hydraulic
system.
WARNING
Perform service in safe work areas.
Never service the Ho-Pac in the trench.
