3.2 Cleanliness

An important item in preserving the long life of the
machine is keeping dirt out of working parts. Enclosed
compartments seals, and filters have been provided
to keep the supply of air and lubricants clean. It is
important that these enclosures are maintained.

Whenever hydraulic and lubricating oil lines are
disconnected, clean the adjacent area as well as
the point of disconnection, cap, plug or tape each
line or opening to prevent entry of foreign material
in the circuit.The same recommendations for
cleanliness apply to electrical and mechanical parts.

Clean and inspect all parts. Ensure all passages
and holes are open. Cover all parts from dust or
liquids. Ensure parts are clean when they are
installed. Leave new parts in their containers until
ready for assembly. Clean the rust preventive
compound from all machined sufaces of new parts
before installing them.

3.3 Handling

When performing repair, do not attempt to manually
lift heavy parts when hoisting equipment should be
used. Never place or leave heavy parts in an unstable
position. When raising a portion of a work platform
or a complete work platform, ensure the work
platform is securely blocked and the weight is
supported by blocks rather than by lifting equipment.

When using hoisting equipment, follow the hoist
manufacturer recommendations and use lifting
devices that will allow you to balance properly the
assemblies being lifted and to ensure safe handling.

Unless otherwise specified, all removals requiring
hoisting equipment should be accomplished using
an adjustable lifting attachment. All supporting
members (cables, chains, straps) should be parallel
to each other and as near perpendicular as possible
to the surface of the top of the object being lifted.

If a part resists removal, ensure all nuts and bolts
have been removed, all electrical or hydraulic
connections have been disconnected, and that an
adjacent part is not interfering.

3.4 Welding from the work platform

It is important to respect the following precautions
when welding from the platform:

- The welder ground wire must be connected

directly to the part to be welded.

- No part of the platform must contact the welding

rods, holders, ground terminals or the structure
being welded.

- Do not ground the welder through the machine

as this could cause arcing inside the mast
assembly.

Any welding on the machine (chassis and
mast assembly) is strictly forbidden.

3.5 Assembly / Disassembly

When assembling or disassembling a component or
a system, complete each step in turn. Unless
otherwise specified, do not partially assemble one
part and start assembling another. Make all necessary
adjustments. Always check the job after it is
completed to ensure nothing has been overlooked.
Recheck the various adjustments by operating the
machine before returning it to the job.

Pressing parts

When pressing one part into another, use an anti-
seize compound or a molybdenum disulfide base
compound to lubricate the mating surfaces.

Parts which are fitted together with tapered splines
or keys are always very tight. If they are not tight,
inspect the tapered splines and discard the part if the
spines or keys are worn.

Assemble tapered parts dry. Before assembling parts
with tapered splines, be sure the splines are clean,
dry, and free from burrs.
