DEFINITION OF SAFETY TERMS AND SYMBOLS
Throughout this manual, the terms DANGER, WARNING, and CAUTION are used to indicate the degree of
hazard to personnel if proper safety procedures are not followed. These words will be used in conjunction with the Safety
Alert Symbol: a dark triangle containing a white exclamation mark.
The Safety Alert Symbol means:
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
DANGER Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
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;
OR
mayalso be used to alert against unsafe practices that may result in personal injury.
ACCIDENTS CAN BE PREVENTED WITH
YOUR HELP !
No accident prevention program can be successful
without the wholehearted cooperation of the person who
is directly responsible for the operation of the equipment.
To read equipment accident reports from all over the
country is to be convinced that a large number of
accidents can be prevented only by operators who
consistently anticipate the results of their actions and
thus prevent accidents from ever occurring. No power-
driven equipment, whether it is on the highway, in a farm
field, or in an industrial plant, can be any safer than is
allowed by the person who is at the controls.
If accidents are to be prevented (and accidents can be
prevented), that prevention will come from equipment
operators who accept their complete responsibility.
The designer, the manufacturer, and the safety engineer
all help create a safe product, but the operator of that
product can wipe out their combined efforts with a single
careless act.
The best safety device is a careful operator. FFC and
your dealer ask that YOU be that careful, responsible
equipment operator.
YOU ARE THE KEY TO SAFETY BECAUSE:
YOU are responsible for the SAFE operation and
maintenance of YOUR AutoRake®.
YOU are responsible to familiarize yourself, and anyone
else who will assemble, operate, maintain, or work
around this product, with the SAFETY information
contained in this manual.
YOU are responsible to read ALL information contained
in this manual to any operators or maintenance person-
nel who are not fully able to read the written English
language. Whether YOU read the manual as written or
translate it into another language, YOU must make cer-
tain that all operators and maintenance personnel have
a complete understanding of the full and exact contents
of this manual. Translations of this manual into other
languages are available by submitting an order to FFC.
YOU can reduce the risk of injury or death by following
all safety precautions and by using good safety
practices.

•Do not roll back this product so far that the load falls off toward or on the operator.
•Do not lock the auxiliary hydraulics of your power unit in the “ON” position.
•Keep everyone at least nine feet away from the unit when operating.
CAUTION
Failure to obey the following procedures may result in personal injury.
•Do not use the top of this product as a step. Under certain conditions, this area can be slippery.
IMPORTANT Attempting to pick up large rocks, large tree branches, etc.
CAN result in damage to this product and
WILL
void all FFC warranties.
IMPORTANT Using this product to till compacted soil
CAN result in damage to this product and
WILL
void all FFC warranties.
Before using this product on an area, make sure that:
•the area is free of all boulders larger than 6” in diameter, all logs and large tree branches, all wire, all lumber, and any
other item that is too large for the bucket or could get wrapped around the rake chain, and
•the soil is relatively loose and any compacted areas have been tilled with another piece of equipment to a depth of 2”
or deeper.
RAKING
Keeping in mind that all raking must be done while moving backward, position your power unit and this product on the
area to be raked. To begin raking:
1. activate the auxiliary hydraulics for operating the rake chain,
(If the rake chain does not move but the hydraulic cylinder begins to retract, then activate the auxiliary hydraulics
in the opposite direction to get the rake chain to operate.)
2. lower the loader arms completely and set the loader arm control in the float position,
3. tilt this product forward until the weight of the rake portion is resting on the depth adjustment plates, and
4. move your power unit slowly backward.
To achieve the best possible results, please keep in mind that:
•If the rake is throwing too much soil into the bucket, then the depth adjustment plates should be placed in a lower hole
on the main housing.
•If the rake is slipping over items that should be collected, then the depth adjustment plates should be placed in a
higher hole on the main housing.
•Multiple passes may be needed to achieve the desired results depending on what those results are and what the
initial conditions are.
•The wide variety of soil types, moisture conditions, compaction levels, foliage densities, and rock and debris
quantities that can be encountered mean that the operator may need to make adjustments based upon the operator’s
experience.
IMPORTANT Opening the main housing and using the bucket for standard bucket operations
CAN result in damage to this product and
WILL
void all FFC warranties.

AUTORAKE®OPERATION (Continued)
SAFETY FIRST!! READ AND UNDERSTAND THE SAFETY
INSTRUCTIONS (pages 2-5 of this manual) BEFORE BEGINNING ANY
AUTORAKE®OPERATION
DUMPING
1. Shut off the auxiliary hydraulics.
2. Move to the dump site and park on firm, level ground.
3. Activate the auxiliary hydraulics in the direction opposite of what was used to operate the rake chain. This will retract
the hydraulic cylinder and open the main housing.
4. Raise this product about four feet above the ground.
5. Dump the bucket and reverse the process so that you are ready to resume raking.
AUTORAKE®MAINTENANCE
SAFETY FIRST!! READ AND UNDERSTAND THE SAFETY
INSTRUCTIONS (pages 2-5 of this manual) BEFORE BEGINNING ANY
AUTORAKE®MAINTENANCE
BEFORE EACH USE
•Make sure that all nuts and bolts are in place and properly tightened.
•Make sure that all other fasteners are in place and are performing their specified function.
•Make sure that all hydraulic fittings are tightened and that there are no leaks in any fittings or hoses.
•Make sure that all safety signs are in place, are clean, and are legible.
(SEE THE SAFETY SIGN SECTION ON PAGE 5.)
•Replace any damaged parts and excessively worn parts. Replace the rake chain when the raking action has been
reduced to an inefficient level.
AFTER EVERY 10 HOURS OF USE
•Grease 11 fittings: one on each of the six bearings (one on each end of the two idler shafts and one on each end of
thedriveshaft),
two on each of the two swing arms where the main housing pivots on the bucket, and
one on the barrel end of the hydraulic cylinder.
AFTER EVERY 30 HOURS OF USE
•Check the drive chain and the rake chain tension and adjust if necessary. (See AUTO-RAKE SERVICE on page 9)
•The proper tension on the drive chain results in the longest run of chain having a 3/8” to 1/2” midpoint deflection.
•The proper tension on the rake chain results in the top run of chain (i.e. from the front idler shaft to the drive shaft)
having a 3/4” to 1” midpoint deflection. (Note: For this chain, the combined up and down midpoint deflection of 1-
1/2” to 2” may be easier to measure.)
•Check the rake chain travel to make sure that the chain is centered on the idlers. Adjust the front idler if centering is
necessary.
AFTER EVERY 250 HOURS OF USE
•Check the drive chain, the drive and driven sprockets, the drive shaft, and the idler shafts for excessive wear and
replace if necessary.
IMPORTANT Using heat to straighten bent rake chain teeth
CAN result in damage to this product and
WILL
void all FFC warranties.
•Check for bent rake chain teeth and cold straighten those teeth.
BEFORE EXTENDED STORAGE (More than 2 month)
•Oil the drive chain and all 3 rake chains.

AUTORAKE®SERVICE
SAFETY FIRST!! READ AND UNDERSTAND THE SAFETY
INSTRUCTIONS (pages 2-5 of this manual) BEFORE BEGINNING ANY
AUTORAKE®SERVICE
1. Park your power unit on a level surface with this product properly attached.
2. Place your power unit’s transmission in “Park” and engage the parking brake.
3. Lower this product onto a level surface.
4. Shut off your power unit’s engine, remove the starter key, wait for all moving parts to come to a stop, and relieve all
pressure in the hydraulic lines.
DRIVE CHAIN ADJUSTMENT
5. Remove four bolts from the drive chain shield. (Two from the top-front face and two from the bottom-rear face.)
6. Remove the shield by pulling straight out to the left.
7. Loosen the nut on the idler sprocket and push the sprocket toward the chain until the opposite chain run (i.e. the
longest) has a midpoint defection of 3/8” to 1/2”.
8. Retighten the idler sprocket nut to 304 ft. lbs., + or - 22 ft. lbs.
9. Recheck the chain deflection and repeat steps 7 and 8 if the deflection is not within the above specified range.
10. Replace the drive chain shield and bolts. Tighten the bolts to 20 ft. lbs., + or - 2.0 ft. lbs.
RAKE CHAIN ADJUSTMENT
5. Loosen the four nuts that secure the bearing on one end of the front idler shaft. Repeat this process for the other end
of the front idler shaft.
6. For each of the two front idler shaft bearings, loosen the jam nut on the 5/8” dia. x 6” long tightener bolt.
7. Tighten the tightener bolts until a midpoint deflection of 3/4” to 1” between the idler shaft and the drive shaft has been
achieved for each of the roller chain portions of the rake chain. (By utilizing a tape measure and a long, slender hook
device, the combined up and down midpoint deflection of 1-1/2” to 2” may be easier to measure.)
8. Retighten the four nuts on each of the two bearings to 84 ft. lbs., + or - 6.0 ft. lbs. and retighten the jam nut on the two
tightener bolts to 169 ft. lbs., + or - 12 ft. lbs.
9. Recheck the chain deflection for compliance with the above specifications and check the chain travel to make sure
that the chain is centered on the idlers. Repeat steps 5 to 8 until both the specified deflection and desired line of
travel has been attained.
