Safety
The RAKE–O–VAC was designed and tested to offer
safe service when operated and maintained properly.
Although hazard control and accident prevention
partially are dependent upon the design and
configuration of the machine, these factors are also
dependent upon the awareness, concern, and proper
training of the personnel involved in the operation,
transport, maintenance, and storage of the machine.
Improper use or maintenance of the machine can result
in injury or death. To reduce the potential for injury or
death, comply with the following safety instructions.
Since the Rake–O–Vac must be towed to operate, it is
extremely important that the tow tractor be carefully
selected to assure the best performance and safe operation.
The tow tractor must have the proper wheel base and tread
width and equipped with a roll bar and seat belt to operate
safely on hilly terrain. The normal operating speed is 6 mph
but will vary with terrain and debris being picked up. The
maximum transport speed is 20 mph with slower speeds
required on hilly terrain. Refer to tractor Operator’s Manual
for information or tractor service agency if you have any
question on safe operation.
The brakes of the tow tractor must have the capacity to stop
the Rake–O–Vac with hopper fully loaded and traveling at
the maximum recommended transport speed.
The power take–off drive of the Rake–O–Vac requires a
tractor with operating speeds of 540 rpm and output power
of 20 hp or higher. Do not exceed the 540 rpm speed.
The Rake–O–Vac must comply with local road
requirements, if transported on public roads. A
Slow–moving vehicle sign has been provided. Signal lights
and brakes are not provided and may be required in some
areas.

fumes may be ignited by a spark.
•Store gasoline in an approved container and
keep it out of the reach of children. Never buy
more than a 30-day supply of gasoline.
•Always place gasoline containers on the ground
away from your vehicle before filling.
•Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
•When practical, remove gas-powered equipment
from the truck or trailer and refuel the
equipment with its wheels on the ground.
•If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline dispenser
nozzle.
•If a gasoline dispenser nozzle must be used, keep
the nozzle in contact with the rim of the fuel
tank or container opening at all times until
fueling is complete.
Check Tire Pressure
Check tire pressure daily to assure proper level.
Correct tire pressure is 28 psi.

another, support flex tip reel, broom or thatching reel.
with transport hooks.
Adjust Reel Support Arm
When machine is operated, gauge wheel should ride over
the turf evenly. If reel support arm has a tendency to
bounce, spring setting is too tight. If gauge wheel scars turf,
spring setting is too light.
To adjust reel support arm:
1. Pull rake lever rearward to lower flex tip reel or broom.

2. Counterbalance spring 3. Adjustment screw
2. Position a spring scale on transport hook and lift up.
Tension necessary to lift gauge wheel off ground should
be 30–50 lbs.
3. If tension is not 30–50 lbs., adjustment is made by
tightening or loosening adjustment screw on
counterbalance spring.
4. Perform this procedure on both sides of sweeper.
Note: Because of added weight of drive components, the
R.H. spring will require a tighter setting than the L.H.
spring.
Adjust Rake Depth
Flex tip reel should be adjusted so rake tips slightly touch
surface but do not penetrate turf. If rake tips penetrate turf,
improper debris pickup could result.
1. Position sweeper on a level surface.
2. Loosen locknut on depth adjustment bolt so it can be
turned.

Operating Tips
•Before starting to sweep, survey area to determine the
best direction to sweep.
Note: To maintain a straight line when sweeping, sight of
an object in the foreground.
•Always try to make a long, continuous run with a slight
overlap on the return run.
•On turf areas, the flex tip reel will pick up twigs,
clippings, leaves, pine needles and cones, small debris
(beverage cans, small bottles, paper plates, etc.).
•The rake teeth are made of flexible nylon and easily
changed. To prevent damage, the rake is protected from
solid obstructions by spring action. The nylon teeth will
not mar bronze, stone markers, sidewalks or pavement.
•Because of its unique design, the sweeper also grooms
the turf. The flex tip reel combs through and lifts grass
for a uniform cut when mowed. As it cleans, the light
scarifying action increase water and pesticide
penetration, thus reducing the need for renovation.
Important Do not make sharp turns when using the
thatching reel as damage to turf may occur.
Important Do not operate sweeper while reel is turning
and in the raised position. Damage to the rake and tires may
result if teeth come in contact with tires.
This product may exceed noise levels of 85 dB(A)
at the operator position. Ear protectors are
recommended, for prolonged exposure, to reduce
the potential of permanent hearing damage.
Caution
•To empty hopper, pull tailgate latch rope.
Inspection And Cleanup After
Operation
•When sweeping has been completed, thoroughly clean
and wash the machine. Air dry hopper. After cleaning, it
is recommended that the machine be inspected for
possible damage to mechanical components and blower.
These procedures will assure that the machine will
perform satisfactorily during next sweeping operation.
Important When towing sweeper for long distances,
fasten gauge wheel arm securely to sweeper frame with
transport hooks. Should gauge wheel arm fall to ground,
damage to sweeper may occur.

Maintenance
Note: Determine the left and right sides of the machine
from the normal operating position.
Important Refer to your engine operator’s manual for
additional maintenance procedures.
Lubrication
The Rake–O–Vac has grease fittings that must be lubricated
regularly with No. 2 General Purpose Lithium Base Grease.
Lubricate bearings after every 30 hours of operation or
whenever machine is washed with water. Bearings and
bushings must be lubricated daily when operating
conditions are extremely dusty and dirty. Dusty and dirty
operating conditions could cause dirt to get into the
bearings and bushings, resulting in accelerated wear. The
grease fittings that must be lubricated are the gauge wheel
bearings (2) (Fig. 19); reel shaft bearings (2) (Fig. 19);
impeller shaft bearings (2) (Fig. 20); Jackshaft bearings (2)
(Fig. 21) left and right trailing arms (1 ea.) (Fig. 21) front
and rear drive shafts (6) (Model 07052 only)
(Fig. 22 & 23).
1. Wipe grease fittings clean so foreign matter cannot be
forced into the bearing or bushing.
2. Pump grease into the bearing or bushing.
3. Wipe up excess grease.
Figure 19
Figure 20
Figure 21
To lubricate drive shafts:
1. Disconnect sweeper from P.T.O. shaft on prime mover.
