RAM USE AND CARE
1. Do not force the ram. Use the correct
ram for your application. The correct
ram will do the job better and safer at
the rate for which it is designed. Do not
force the ram and do not use the ram for
a purpose for which it is not intended.
2. Store idle rams out of reach of children
and other untrained persons. Rams are
dangerous in the hands of untrained
users.
3. Maintain rams with care. Keep
rams clean. Properly maintained
rams are less likely to bind, break or
malfunction. Do not use a damaged
ram. Tag damaged rams “Do not use”
until repaired.
4. Check for misalignment or binding of
moving parts, breakage of parts, and
any other condition that may affect
the ram’s operation. If damaged,
have the ram serviced before using.
Many accidents are caused by poorly
maintained rams.
5. Check all hydraulic connections and
hoses before applying pressure to the
Ram.
6. Do not leave the ram unattended when
it is pressurized. Release pressure on
the ram before leaving work area.
7. Do not exceed working pressure.
8. If lifting, support load properly when
finished.
9. Follow hydraulic pump instructions.
10. Do not use for aircraft purposes.
SERVICE
1. Ram service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could result in a risk of injury.
2. When servicing a ram, use only identical
replacement parts. Follow instructions
in the “Inspection, Maintenance, And
Cleaning” section of this manual. Use
of unauthorized parts or failure to follow
maintenance instructions may create a
risk of electric shock or injury.
3. Maintain labels and nameplates on the
ram. These carry important information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
4. Repairs or adjustments to hydraulic
systems should only be performed by a
qualified technician.
