9. Maintenance and Inspection
WARNING - The equipment must be inspected
according to the requirements of this section. Failure
to properly inspect the equipment could lead to
severe injury or death. The equipment must be
removed from service and inspected immediately if it
is subjected to an abnormal load or a shock load. If
any irregularities or problems are detected during an
inspection, the equipment must be removed from
service immediately and repaired. Contact the
manufacturer at the numbers and address printed on
the back cover of this manual.
9.1 Inspection
The owner must inspect, or appoint a knowledgeable
person to inspect the unit for signs of corrosion and / or
excessive wear. Visual inspection should be made
before each use of the unit, checking for abnormal
conditions. Regular inspections should be made weekly
for daily use and monthly for intermittent use. Each unit
must be inspected immediately if subjected to an
abnormal load or shock. Any unit which appears to be
damaged in any way, is found to be badly worn, or
operates abnormally shall be removed from service until
necessary repairs are made.
Inspect the door for closure and door handle latching
operation. The door should close easily and the door
handle should loosely latch with a 90-degree rotation
of the door handle. Further 90-degree rotation of the
handle should clamp the door shut and actuate the
control valve. There should be the sound of air
flowing for up to 45 seconds until the ram is fully
lowered and the air pressure in the ram cylinder
equalizes with the air supply.
After the air stops flowing, check the unit for
excessive leaks. An excessive leak is a leak which
can be heard and which degrades the performance
of the unit. Minor leaks do not adversely affect the
operation of the unit.
Unlatch the door and the air should exhaust from the
ram cylinder. The door should not open until the ram
has
returned to its fully raised position
(approximately 10 seconds).
Inspect crushing chamber for damage or worn parts.
If any irregularities or problems are detected during
an inspection, the unit must be removed from service
immediately and repaired. Contact the manufacturer
using the contact information on the back cover of
this manual.
9.2 Maintenance instructions
WARNING - All inspection and maintenance procedures
must be performed after the equipment has been removed
from service. Failure to do this may result in personal injury
and/or property damage.
All warning and capacity labels should be readable
and complete. Wash external surfaces of jack, labels,
and decals with a mild soap solution.
Lubricate all rotating and sliding portions of the jack
monthly.
9.3 Control valve actuation adjustment
Note: The setscrew on the door that actuates the
control valve and the pawl on the door handle latch
are adjusted at the factory and should never need
adjustment.
1. Make sure the two screws securing the control valve
on the right hand side of the unit are tight. Make sure
the two screws securing the handle latch to the door
are tight and the two jam nuts securing the latch pawl
to the stem are tight.
2. Loosen the jam nut securing the set screw on the
door and back the setscrew out. Close door and turn
door handle fully clockwise to solidly latch the door.
3. Using a hex wrench, slowly tighten the setscrew until
the top platen lowers and there is no air leakage
detected around the spool of the control valve.
Tighten the setscrew 1/2 turn further and secure the
setscrew with the jam nut.
4. Rotate the latch handle 1/4 turn counterclockwise.
The air should exhaust and the ram should retract, but
the pawl should remain loosely engaged with the door
closed.
5. Rotate the latch fully counterclockwise and the door
should open. Repeat steps 2 through 5 if the door
does not operate correctly.
