ULTRAHOOK UHR40 VEHICLE RESTRAINT
LUBRICATION:
As shown by Figure 19: Lubrication Points on page 23, the indicated pivot points of the Vehicle
Restraint must be lubricated regularly to help maintain the unit in proper working condition. The recommended
lubrication
service interval is every 30 days
or at a greater frequency as required in severe environments.
Hydraulic Oil:
The oil should be changed once a year under normal operating conditions. The oil level, however,
should be checked weekly. When the hook is fully retracted, the oil level in the reservoir should be approximately 2 - 3
inches from the top.
NOTICE: HYDRAULIC FLUID
The standard hydraulic oil supplied with the equipment is HVI-22 Hydraulic fl uid. This fl uid is suitable for use from
approximately -30º C (-22F) minimum to +35ºC (+95ºF) unless otherwise specifi ed on the specifi c equipment
order. The equipment can be operated in temperatures slightly higher and lower than the temperatures stated on
an intermittent basis. Operating the equipment for extended periods of times at temperatures higher or lower than
the stated temperatures above may result in functional issues for the equipment. It may also result in damage and
issues to hydraulic components. As the actual temperature the equipment is used in moves further away from
the recommended temperature range the concern points increase. Abuse and overuse in this regard will void all
warranty.
The standard replacement Hydraulic Fluid is HVI-22 hydraulic fl uid which accommodates the temperature range
stated above. There are special hydraulic fl uids available to accommodate temperatures that are consistently and
or signifi cantly lower or higher than those stated above. In many cases the use of these types of specialty fl uids
will result in the requirement for hydraulic fl uid changes during seasonal yearly temperature changes.
Recommended for colder temperatures is Hydraulic Fluid 5606A
If the hydraulic oil provided from the factory is non-standard, refer to the hydraulic reservoir fl uid label which will
specify the particular oil requirements.
Note:
When approaching or operating in temperature beyond the high and low temperature ranges of the
ratings for the hydraulic fl uids, there may be some adverse eff ects to the functionality of the equipment. This
could include (but not be limited to) harmonics and vibration of cylinders, inhibited or reduced equipment
performance and function, slower cycle times, hydraulic leaks unwanted activation of velocity fuses. To address
concerns of this nature a change in hydraulic fl uid or a special oil additive maybe required. Contact your Pentalift
representative for more information.
