SAFETY WARNINGS
HL-800 HYDRAULIC DOCK LEVELER
LOCKOUT/TAGOUT PROCEDURES
The Occupational Safety and Health Administration (OSHA) requires that, in addition to posting safety warnings and
barricading the work area, the power supply has been locked in the OFF position or disconnected. It is mandatory
that an approved lockout device is utilized. An example of a lockout device is illustrated. The proper lockout
procedure requires that the person responsible for the repairs is the only person who has the ability to remove the
lockout device.
In addition to the lockout device, it is also a requirement to tag the power control in a manner that will clearly note
that repairs are under way and state who is responsible for the lockout condition. Tagout devices have to be
constructed and printed so that exposure to weather conditions or wet and damp locations will not cause the tag to
deteriorate or become unreadable.
RITE-HITE PRODUCTS CORPORATION does not recommend any particular lockout device, but recommends the
utilization of an OSHA approved device (refer to OSHA regulation 1910.147). RITE-HITE PRODUCTS
CORPORATION also recommends the review and implementation of an entire safety program for the Control of
Hazardous Energy (Lockout/Tagout). These regulations are available through OSHA publication 3120.
This is a statement of serious hazard. Failure to
follow the listed instructions could place the
individual at risk of serious injury or death.
WARNING
!
This is the highest level statement. Failure to
follow the listed instructions will most likely
result in severe injury or death.
DANGER
!
The statements used with this level of
warning deal with a safe operating
procedure. If the procedure is ignored, the
possibility of personal injury may exist.
CAUTION
!
IMPORTANT is used to draw attention
to a procedure that needs to be followed to
prevent machine or property damage.
IMPORTANT
When working with electrical or electronic
controls, make sure that the power source has
been locked out and tagged according to OSHA
regulations and approved local electrical codes.

1. Check pit to ensure it meets RITE-HITE pit details #0108172. If pit does not match pit details, contact your local
representative or RITE-HITE before proceeding.
2. Leave shipping bands on leveler until instructed to remove them.
3. Verify that the leveler voltage matches the voltage supplied at pit. Remove control box from frame if it has not already
been installed.
4. Clean out pit and remove all debris from work area.
5. Handling Plates (see Detail "B") must be inserted into the forward handling holes of the toeguards. See Details "C".
6. Attach lifting chain, lift leveler and position above pit. Lower leveler into pit. See Detail "C".
7. Center leveler in pit so that equal gaps are maintained on each side of leveler. See Detail "D".
8. Push leveler straight back until the front frame angle is flush with the front curb angle. If the pit is not square, push
the leveler straight back until the front frame angle is completely behind the front curb angle by no more than 1/4 inch.
The front frame angle should never extend past the front curb angle. If unit cannot be pushed back far enough, the
back edge of the rear frame angle can be cut off up to 3/8 inch. If trimming back edge of angle does not allow frame
to be positioned properly in pit, contact contact your local representative or RITE-HITE for assistance. Tack weld rear
frame angle to rear curb angle. See Details "D" & "G".

below dock floor, and add shims. See Detail "K".
12. Remove and discard shipping bands from lip.
13. Place marks on the face of the front frame angle to indicate the frame centerline and the location of each below
dock stop channel. Also, place a mark on the face of the lip to indicate the lip/platform centerline.

18. Cut and place shim(s) between the frame channels and pit floor directly under the ramp cylinder pivot.
Do not weld shims at this time! The frame channels will be level between the rear frame and the ramp
cylinder pivot with the proper shim height. See Detail "J" and "K".
19. Weld all stacked shims together. Weld rear shims to the rear frame. Weld shim(s) to the frame channels
under the ramp cylinder pivot. Weld shims to the front curb angle and front frame angle. See Detail "M"
& "N".
20. Stitch weld the rear frame angle (and the rear spacers if needed) to the rear curb angle. See Detail "H"
& "L". Center a 6 inch weld behind each support post and a 3 inch weld at each end of rear frame angle.
21. Clean and paint all weld and grind marks.
22. Remove front shipping bolt from each full range toeguard. Verify that toeguards move up and down freely.
