SAFETY
A product safety sign or label should alert persons to a specific hazard, the degree or level of hazard
seriousness, the probable consequence of involvement with the hazard, and how the hazard can be
avoided. SIGNAL WORD is a word or words that designate a degree or level of hazard seriousness. The
signal words for product safety signs are “DANGER, WARNING, CAUTION” and “NOTICE”. Below is
each of these signal words along with their definitions as directly referenced from ANSI Z535.4-1998.
!
DANGER
Indicates an imminently hazardous situation which, if not avoided, will result in death or serious
injury. This signal word is to be limited to the most extreme situations.
!
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious
injury.
!
CAUTION
Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe practices.
NOTICE!
“NOTICE” is the preferred signal word to address practices not related to personal injury. The safety alert
symbol shall not be used with this signal word. As an alternative to “NOTICE”, the word “CAUTION” without
the safety alert symbol may be used to indicate a message not related to personal injury.

means other than described in the operation
procedures contained in this manual. Keep all body
parts clear of the ramp at all times and maintain a
safe distance from the underside of the ramp while
raising or lowering.
DO NOT operate the ramp if operation causes
undue physical strain or if physical impairments
could lead to undue strain in back, muscles, limbs or
joints.
DO NOT use ramp if either of the chains are missing
or if the chains are not securely in place.
NEVER crawl or work under, walk or drive on any
ramp that is not resting on and chained to a suitably

DO NOT use drive on or place any weight on ramp if
release valve on pump is in the closed position.
DO NOT use ramp if carrier wheels are not chocked
and support jacks under the trailer are not being
used.
Many trailers have air ride suspensions that may
cause the trailer to move away from the ramp during
loading and unloading operations. The potential for
this movement can be reduced by exhausting or
“dumping” the air from the air ride suspension
system before servicing the trailer. Make sure
attached chains are used to secure the ramp to the
trailer.
NEVER permit a carrier to pull away and allow the
ramp to fall to the ground.
ALWAYS store the ramp in the lowered position.

hydraulic port is clear and open). Place cylinder in
position, making sure that the port is at the top.
Replace cylinder retaining pins and spacers.
Replace hydraulic line, but do not tighten fitting.
With release valve still in the open position, use a
fork truck to raise the lip end of the ramp clear of the
support. Remove the support and slowly lower the
ramp into its lowest position. Bleed the hydraulic
system as described previously, tighten hose
fittings, and add oil as required. (Refer to bleeding
instructions above)
1. HYDRAULIC HAND PUMP/RESERVOIR:
The hydraulic system is factory filled and the vent/
petcock valve is closed for shipping. However, if at
some time fluid needs to be added, follow this
procedure: With the ramp in the fully lowered
position, remove the filler plug from the top of the
pump reservoir. Be sure to clean away any foreign
matter so as not to contaminate the fluid in the
reservoir. Contaminated fluid is the leading cause
of hydraulic system malfunction.
NOTICE!
4. REMOVING HYDRAULIC PUMP:
Use only genuine Enerpac hydraulic oil. The
use of any other fluid will render your warranty
null and void.
!
The ramp must be in the fully lowered position
before starting removal. Disconnect hose from the
pump. (See Figure #5)
CAUTION
Remove four (4) hex nuts at the base of the pump
reservoir. Take pump off of the bracket. To replace
the pump, reverse the procedure. After the pump is
installed and attached to the system, bleed the
hydraulic lines, add oil as required.
During line bleeding do not allow the ramp to
raise, the ramp could fall suddenly causing
death or serious injury.
2. LINE BLEEDING:
RUNNING GEAR
After filling the reservoir or performing other
maintenance of the hydraulic system, it may be
necessary to bleed the system of entrapped air.
The pump must be at its fully lowered position.
Loosen the hose fitting at the cylinder farthest from
the pump and, with the release valve closed, slowly
operate the pump until the oil flows clear without a
sign of air bubbles. Tighten the hose fitting. Repeat
the process at the cylinder nearest to the pump.
Add oil to the reservoir as required.
When preparing to work on any part of the wheel or
axel assembly, start with the ramp in the lowest
position. The pump release valve must be open.
Lift the ramp at the lip end with a fork truck or other
suitable means until wheels are slightly off the
ground. FOLLOW BLOCKING INSTRUCTIONS.
5. REMOVING WHEELS:

the procedure above.
Do not leave the flow control valve in the closed
position. This will cut off fluid flow back to the
pump. This will be an unsafe condition. Do not
use the ramp if it will not lower onto the carrier.
7. STEEL CONTAINERAMP FRAME:
Failure to do so may result in death or serious
injury.
Annual inspection of the steel frame’s enamel finish
should be performed. Any areas indicating rust
should be thoroughly wire brushed, prime painted,
and top coat painted with a good quality rust
inhibiting coating. All steel products will begin to
show signs of weathering at some point. This
general “touch-up” is not to be considered a claim
against the products warranty.
