• Cable anchors on Bloom winches are not designed to hold the rated load of the winch. You must keep at least five (5)
wraps of cable on the drum to ensure that the cable doesn’t come loose. We suggest that the last 5 wraps of cable be
painted bright red to serve as a visual warning.

• Stay clear of suspended loads and of cable under tension. A broken cable or dropped load can cause serious injury or
death.

• No equipment should be installed, operated, or maintained by any person who has not carefully read all contents of this

CAUTION

A winch, like other types of machinery, needs to have regular maintenance if it is to perform properly, give lasting service,and
provide safe winching.

(a) Clean and Inspect:

cause skin rashes. If necessary, use rubber gloves. Inspect all parts for wear, nicks, scratches and damage that would
render them unusable. If a part is questionable, it is better to replace it rather than take a chance on premature failure
when the winch is placed back in service. Always replace O-rings and seals, and it is a good idea to use new roll pins
as well. Sometimes it is permissible to reuse bearings and bushings...it depends on how much use they have had. The
rollers should not exhibit any surface irregularities. If the rollers show any sign of spalling, corrosion, discoloration,
material displacement or abnormal wear, the bearings should be replaced.
Likewise, the cage should be inspected for unusual wear or deformation, particularly the cage bars. If there is any
damage that will impair the cage’s ability to separate, retain, and guide the rollers properly, the bearing should be
replaced. The thrust washer contact areas should be free from any surface irregularity that might cause excessive
abrasion or friction. If the winch was disassembled only to replace damaged seals after a short period of service, it is
not necessary to replace the bearings. Experience and common sense, along with a good inspections, will determine if
they can be used again. Always coat O-rings, bearings, bushings and the rubber parts of seals with oil during assembly.

(b) Oil Change Information:

The winch vent/fill and drain plugs are located at the base of the face plate. Oil should be changed every 100 hours of
operating time, or every six months, whichever comes first.

(c) Oil Level:

To check the oil level, remove the level plug. The oil should be level with the bottom of this opening. If more oil is
needed, use the recommended gear oil listed below.

Use BLOOM ULLTRA-LUBE NO. 601 trans-worm gear oil; available from Bloom in pints or quarts. For emergency
situations when BLOOM ULLTRA-LUBE NO. 601 is not immediately available, use Phillips 66 Company SAE grade
80W90 superior multi-purpose gear oil (Phillips 80W90 SMP) meeting API classification GL-5 or equivalent brand.
Continuous use of oil other than BLOOM ULLTRA-LUBE NO. 601 or Phillips 80W90 SMP oil may shorten the life of the
gears. DO NOT mix BLOOM #601 or Phillips 80W90 SMP with more than 50% of any other kind of oil.

• Winches, like any other kind of machinery, require a “break in” to perform well and to
maximize their life.

high speeds when performing this operation.

• Make sure that the cable is unrolled in a line (to prevent kinks) and slowly inhaul the
winch to install the cable.

CAUTION

• Do not exceed one half rated load or one half rated line speed for the first thirty
minutes of operation. This will ensure that the worm and gear have an opportunity to
wear in properly.

• Periodically, check the gearbox for temperature rises and allow the winch to cool
down between pulls.

Winch Installation

properly and to ensure safe operation.

• The mount must be flat to ensure proper alignment between the gearbox side, the
drum, and the clutch.

• Winches must never be fastened directly to the frame of a truck. Mounting
brackets should be used.

• With a hydraulically driven winch, make sure the hydraulic system is clean and that
all components function properly, especially the relief valve.

Winch Operation

• To familiarize yourself with the winch, run it for a few minutes to understand the controls and the “feel” of the winch.

• Pay particular attention to the controls and how they operate. Make sure you understand which way the winch will
rotate when the control lever is moved.

• Always make sure that all people are clear of the load and of the cable area before beginning a winching operation.

• Ensure that proper protective wear is worn while operating winch.

• A broken cable can fly in any direction.

•

• If you have any doubts about the capability of the winch to lift or move a load, either put a “snatch block” in the line or
get a bigger piece of equipment.

Winch lifting application:

(1)Attach winch cable to load.
(3)Begin winching the load slowly, watching carefully to ensure that the load is moving normally.

(4)When the load is positioned where you want it, stop the winch.

Consult your local cable supplier for recommendations on the best type of cable

and hardware to use in your specific application.

As the number of layers of cable on a winch increases, the rated lifting capacity of the winch goes down. If you are

Never use larger or smaller cable on your winch than is recommended for it. The use of larger cable will not allow you to

PROPER WRAPPING

pull larger loads and may, in fact, break easier than the proper size cable. The use of smaller cable may overheat the
winch due to the increased running time with more cable.

(b) The Importance of a Proper Fleet Angle:

Maintaining the proper fleet angle is important to the success of your winching operation, the life of your winch and the
life of the cable you are using. The fleet angle can best be described by the following diagram:
The fleet angle should be kept as small as possible to ensure proper spooling and to maximize cable and winch life. To
promote even cable spooling, keep the fleet angle below three degrees. Never pull directly against the flange of the
winch cable drum as this may cause the cable or the winch to break. Adherence to these instructions will ensure better
spooling.

(c) Wire Rope Anchor & Wrapping:

Prepare the end of the wire rope as recommended by the wire rope manufacturer. Pass the free end of the wire rope
through the small opening of the cable drum anchor pocket. Lock the cable into the drum by tightening the cable anchor
set screw.

(d) Automatic Safety Brake:

Some Bloom winches are equipped with an automatic hydraulic brakes to hold suspended loads. If your winch is not
equipped with one, it is intended for pulling loads only . If you wish to lift and suspend loads with your winch, it can be
retrofitted with a brake. Please consult the factory for details. The safety brake is an important feature of your winch and
must be maintained properly.
