throw objects. Failure to observe the following safety instructions could result in
serious injury or death.
3
• Read the manual. Learn to operate this machine safely.
• Always disconnect the spark plug wire and place the wire where it cannot contact the
spark plug, to prevent accidental starting the engine when setting up, transporting,
adjusting or making repairs.
• Keep all shields and guards in place.
• Understand the speed, steering and stability of this machine. Know the positions and
operations of all controls before you operate this machine. Check all of the controls in

OPERATING YOUR NEW CUTTER
The operation of any mower can produce foreign objects to be thrown into the
eyes, resulting in severe eye damage. Always wear certified safety glasses or
wide-vision safety goggles over spectacles before staring any cutting machine and
while operating such a machine.
The operation of any cutter produces sound waves that are damaging to the
human ear. Ear protection is recommended.
OD45- Warning Serious Injury Decal
OD55- Danger- Triangle Decal
CAUTION!
Tragic accidents can occur if the operator is not alert to the presence of
children. Children are often attracted to the machine and the mowing
activity. Never assume that children will remain where you last saw them.
• Disconnect spark plug wire from spark plug and place where it cannot make a connection.
• All engines are filled with oil at the factory. Verify oil level and add if necessary before starting
engine. (See Engine Owner’s Manual)
• Verify fuel level and add if necessary before starting engine.
• Attach swivel hitch(H10TK) to L-Hitch(P/N H1), (See p.10). Then connect trimmer to tow

INTENDED USE
This is not a lawn mower. The Postmaster is designed to trim along fence rows, tree rows, etc.
The Postmaster has been designed to run offset to either side and also offset from the center of
the tow vehicle to provide additional cutting width.
STOPPING THE ENGINE
• Slide the throttle into the “STOP” position.
• Return unit to travel position.
INSTALLING STRING (Refer to OD63- String Diagram Decal)
• Use proper length string. Using a string too long for the unit will cause stalling and
unacceptable operation.
• Remove any built-up debris gathered in string holder.
• Fold string in half, creating a balanced loop.
• Place loop of string against outside of loop on trimmer head.
• Bring ends around and through the loop and over the string loop.
• Pull ends to tighten loop
• Cut string off evenly with outside diameter of the cover to protect fence posts and other
items being trimmed.
STARTING THE ENGINE
• Remove any built-up debris from engine.
• Remove trimmer from travel rest and assemble into desired position.
• Check oil & fuel.
• Prime engine as directed. Note: A warm engine may not need to be primed.
• Slide throttle into “FAST” position.
• Pull engine coil rope. Do not pull recklessly.
• Adjust throttle to desired engine RPM. For maximum results, operate in the full throttle
position.
PREPARING FOR FIRST USE
• Check engine crankcase for oil. Check with engine dipstick. Do not overfill. See engine
manual for proper oil level.
• Fill fuel tank with fresh gasoline. Never fill tank in an enclosed area!
• Check to ensure string has been installed correctly.
• Start trimmer as directed above.
• Under supervision, allow strings to rotate and engine to idle for 5 minutes. This breaks-in
the engine and the belt.
• Stop engine.
OD63- String Diagram Decal
SLOPE OPERATION!
Use extra caution when mowing on slopes. Operate self-propelled units up
and down slopes. There is a significant risk of overturns when operating
across slopes. If you feel uneasy on a slope then do not mow it.

BEGIN TRIMMING
• Make sure area is clear of all bystanders.
• Make sure that all guards, belt guides, and the spark plug wire are properly attached.
• Start engine, setting desired engine speed. Note: This machine is designed to operate at
maximum engine speed.
• Start trimming in a low gear. Some bounce may occur when trimmer is returning into
position. Use caution.
BACKING THE UNIT
• See Transporting.
TRANSPORTING
• Stop engine and remove wire from spark plug.
• Wait for all moving parts to come to a complete stop.
• Place unit into travel position.
• This position is recommended while backing the unit.
•CUTTING HEIGHT
• There are five height settings.
• Stop engine.
• Place unit into travel mode to make adjustments.
• Pull the hairpins and clevis pins out and set both rollers at equal settings.
• Replace hardware.
TENSION ADJUSTMENT
• Spring return-tension should be increased before trimming dense-grass areas.
•Always stop engine while making adjustments.
• Place unit into travel position to make adjustments.
• Move snap hook on chain closer to spring to increase tension.
• Move snap hook to the end furthest from spring to lessen tension.
•Always have chain and spring attached at both ends.
HITCH OFFSET ADJUSTMENT
• Take unit out of travel position.
• Pull ball-lock-pin out of hitch, pivot hitch left or right into the desired offset.
• Replace pin securely, assuring that it locks into position.
• Offset to the opposite side by un-hooking chain connector on the roller bracket. Pivot deck
around to other side and re-attach to opposite roller bracket.
CAUTION!
SHUT OFF ENGINE AND REMOVE WIRE FROM SPARK PLUG BEFORE
MAKING ANY ADJUSTMENTS TO THE UNIT.

SUGGESTED PRACTICES
• Always operate engine at full throttle when cutting to assure the best cutting performance
and proper discharge of material.
• Offset unit to the right-hand side whenever possible (as shown). Debris is thrown away from
the operator.
• If grass is wet, allow it to dry. Wet grass will clump and collect, clean unit regularly.
• When cutting dense areas go slow. Some dense areas may need to be gone over twice.
• Do not operate trimmer if it vibrates abnormally. Excessive vibration is a sign of damage.
Stop the engine and safely check for damage. Repair as necessary.
• For best results, Do not insert cutting head more than halfway through the fence line.
TRIMMER MAINTENANCE & SERVICE
CAUTION!
SHUT OFF ENGINE AND REMOVE WIRE FROM SPARK PLUG BEFORE
MAKING ANY ADJUSTMENTS TO THE UNIT.
USE PROPER TOOLS FOR ANY ADJUSTMENTS,
DISASSEMBLY, OR REPAIRS.

STORAGE
• Do not store engine indoors or other poorly ventilated areas.
• If unit is to be stored for longer than 30 days, prepare as directed below:
Drain fuel outside into an approved container.
Start engine and run until unit is completely out of fuel. Removing fuel prevents
gum deposits from forming inside carburetor. Gum deposits can malfunction the engine.
Let engine cool.
SEASONAL MAINTENANCE
• Replace the spark plug.
• Clean or replace the air filter and fuel filter.
• Change oil.
• Check belts, tires, hardware, etc. for wear and damage. Repair as necessary.
• New spark plug, clean air filter, and clean fuel filter assure proper air-fuel mixture and help
engine perform better and last longer.
BEFORE EACH USE
• Check and fill engine oil on a level surface. If oil appears black or soiled, change
immediately.
• Check condition of filters, spark plug, tires, etc. Clean or replace if necessary.
• Replace/repair strings as necessary.
• Check for loose hardware and tighten as needed.
BELT REPLACEMENT
• Stop engine and remove wire from spark plug.
• Remove belt cover.
• Move idler pulley to free belt and hold.
• Remove old belt.
• Install new belt. Start at the engine pulley and work the belt around the drive pulley and
onto the backside of the idler pulley.
• Release idler pulley.
• Replace belt cover.
