During short-term storage of a HIH, the
following should be taken into consideration:
•
Cover any pressure openings and
open threaded holes with suitable
caps.
• Protect the unpainted surfaces from
dirt and moisture.
• The hammer should not be stored in
an area with substances that have an
aggressive corrosive nature; solvents,
acids, alkalies and/or salts.
For long-term storage (over 9 months), the
following additional actions are recommended:
•
Damages to surface paint must be
repaired before item is stored.
• Protect the unpainted surfaces with
suitable anti-corrosion treatment
such as CRC SP-350, CorrosionX
corrosion inhibitor, or WD-40 Long
Term Corrosion Inhibitor.
• Fill the power unit completely with
hydraulic fluid.
If these instructions are followed to the letter,
the hammer may be stored for approximately
2-years. However, as storage conditions do
have a significant effect, all suggested time
frames should be considered as guide values
only.

Maintenance Conditions and Storage
Oil Recommendations
Hydraulic Oil Cleanliness
When adding or changing hydraulic fluid,
APE uses only Biodegradable Envirologic 146
hydraulic fluid. Consult your local oil supplier
for recommendations on mixing hydraulic oils.
See the warranty document at the beginning of
this manual concerning fluid cleanliness, and
Understanding ISO Codes at the rear of this
manual.
New hydraulic fluid is NOT clean oil!
Oil must meet ISO cleanliness code 17/15/11
Severe Conditions
The servicing intervals are specified on
normal operation conditions. Operation under
severe conditions require shorter service
intervals.
•
When the average outside temperature is
above 80 F (26 C) or below -10 F (-23 C),
reduce service time intervals by one-half.
•
When operating in the presence of dust
or sand, reduce service time intervals by
one-half.
•
When operating in air with high salt or
moisture the service intervals do not need
to be changed. However the unit should
be inspected weekly to determine if
additional servicing is required.
