4.5 WHEEL BEARING LUBRICATION
Using a pressurized lubrication gun and a lithium based
lubricant, lubricate the wheel bearings. This procedure
should be done at the time of setup and also after every
25 hours of service.
NOTE: During setup, each wheel cavity should be filled.
The cavity is full when lubricant is seen coming out
of bearing.
4.6 BLADE HEIGHT ADJUSTMENT
Blade height is adjusted by loosening the locking lever
and turning the adjusting knob to raise or lower the front
wheels. See Figure 7.

FIGURE 7
1. Locking Lever
2. Adjusting Knob
After installing any reel, make the first adjustment on a
hard level surface.
Adjust the blades to 1/8” (3 mm) above the surface. Test
this setting on a small area, then adjust the blades to turf
conditions as required. Each number on the adjustment
decal represents a change of 1/8” (3mm).
If the desired blade position cannot be obtained by
adjusting the front wheels, the rear wheels can be
adjusted. Mounting the wheels in the top hole lowers the
blades and mounting the wheels in the bottom hole
raises the blades.
The front axle may be locked in the down position to
prevent the floating action if desired. Install and secure
1/2” screws, washers, lockwashers and nuts in the slots
above the axle. This will prevent the axle from moving.

5 OPERATION
WARNING
!
DO NOT operate this equipment until you have
thoroughly read and understand the operation
section of this manual.
DO NOT operate this equipment without all
shields in place.
DO NOT make any adjustments or perform any
maintenance while the engine is running.
Always run unit engine where there is plenty of
fresh air to prevent a buildup of carbon monox-
ide fumes. Carbon monoxide fumes are color-
less, odorless and deadly. NEVER run unit in
an enclosed space where exhaust fumes may
collect.
Always stop engine and DO NOT smoke or
allow open flames or sparks when refueling.
Gasoline is extremely flammable and highly
explosive under certain conditions.
Any warning decal that becomes illegible must
be replaced immediately.
To prevent injuries from thrown blades,
NEVER operate the unit with reel blades that
are missing, cracked, badly bent or in any type
of abnormal condition.
Inspect the area to be raked before operating.
Remove any objects that may present a safety
hazard or damage the equipment.
To prevent injury from rotating blades, NEVER
place hands or feet beneath the unit.
This unit is not self propelled by a mechanical
drive system. However, under some condi-
tions the reel rotation may cause the unit to
move under it’s own power.
Engage the reel ONLY when you are in the
proper operator’s position behind the handle.
The clutch bail is designed to be held by the
operator to keep the reel belt engaged ONLY
during use. DO NOT clamp or fasten the bail to
the handle. If the reel is allowed to rotate while
the operator is not in the proper operating
position, the unit may move on it’s own. This
will create an unsafe situation in which the
operator and/or bystanders may be injured.
5.1 DAILY PRE-OPERATION CHECK
1. Visually check for loose or damaged parts and
fasteners. Repair or replace as needed before unit is
placed into operation.
2. Check the reel for bent or broken blades; replace as
necessary.
3. Check engine oil level. Add oil if necessary, following
the engine manufacturer’s recommendations. Refer
to engine manual included with literature packet.
4. Fill the fuel tank with the amount and type of fuel
recommended by the engine manufacturer.

5.3 TIPS FOR OPERATING THE UNIT
•Start the unit in motion before engaging the reel to
prevent unnecessary damage to the turf and to avoid
bogging down the engine. Disengage the reel before
stopping forward motion.
•Make all passes across the turf at a uniform speed.
•Disengage the reel at the end of each pass and before
slowing or stopping to make a turn. This prevents turf
damage while turning the unit.
•If the engine bogs down while going through a thick
patch of turf, push down on the handle just enough to
raise the reel and allow the engine to return to normal
speed.
NOTE: Never cross hard objects or surfaces
(sidewalks, driveways, stepping stones, etc.) with
the reel engaged. Severe blade damage may occur.
5.4 REELS AND SUGGESTED USES

WARNING
!
When replacement parts are required, use
genuine RYAN parts or parts with equivalent
characteristics, including type, strength and
material. Failure to do so may result in product
malfunction and possible injury to the
operator and/or bystanders.
6.1 BELT REPLACEMENT
Belt tension is maintained by a spring loaded idler,
controlled by the clutch bail. No belt tension adjustment
is necessary when proper belts are used.
NOTE: A matched pair of belts must be used for correct
operation. If one belt needs to be replaced, you
MUST replace both belts to assure proper belt
tension.
1. Remove belt guards and old belts from unit.
2. Place the new belts between the idler pulley and the
snubber on the idler arm and then over the engine
and reel pulleys. See Figure 9.

3. Belt Stop Rod
3. Install the belt guards. Make sure the belt stop rod is
outside of the belt. See Figure 9.
6.2 LUBRICATION
The reel and idler pulley bearings are factory sealed and
require no lubrication.
Wheel bearings have lubrication fittings and require
lubrication with a standard lithium based lubricant after
every 25 hours of use.
6.3 BLADE REPLACEMENT
Fixed Blade Reels
To replace worn or damaged blades or to change to
different blade and/or spacer combination:
1. Remove the entire reel from the chassis.
2. Remove bearing from end of shaft (opposite the
pulley end). Loosen the set screw securing the
locking collar. With a small punch, tap the bearing
approximately one quarter turn in the opposite
direction of the reel rotation. This relieves the cam
lock action of the bearing and it can be removed from
the shaft.
3. Hold the shaft to keep it from turning and remove the
shaft nut. Remove the blades and spacers from the
shaft and replace or rearrange as required.
NOTE: When reassembling the reel, it is important to
start and end with a spacer. DO NOT assemble with
a blade next to the shaft nut at either end.
Fixed blades must be placed on the shaft in a
pattern 60°off center from the previous blade. See
Figure 10.
FIGURE 10
4. Re-install the shaft nut and tighten securely to keep
the blades from coming loose.

5. Re-install the reel bearing by exactly reversing the
steps taken to remove it.
NOTE: Blades that are worn on one cutting face may be
reversed and used again.
Flail Blade Reels
Work on only one of the six blade shaft assemblies at a
time.
1. Remove the cotter pin from one end of one of the
blade shafts and pull the shaft out.
2. Replace the blades and other worn parts and
re-assemble in the proper order while sliding the
shaft back into place.
3. Install a new cotter pin to secure the shaft.
6.4 BELT GUARD ROD ADJUSTMENT
There are two belt guard rods mounted in the belt guard.
The long rod helps to prevent the belts from slipping off
the engine pulley. The short rod (belt stop rod) acts as a
belt brake when the clutch bail is released, ensuring that
the reel stops quickly.
It is important that these two rods are adjusted correctly.
If the belt guard is removed for any reason, make sure
the two rods are positioned at the end of their respective
slots. See Figure 11.
