SAFETY INSTRUCTIONS
DANGER: Failure to observe safety instructions and reasonable safety practices can
cause Property Damage, Serious Bodily Injury and/or Death. BE CAREFUL!! WATCH OUT FOR
BYSTANDERS!!
DANGER: NEVER dig trenches where there is a possibility of underground power cables
or other hazards. The exact location of underground services must be determined prior to
drilling. Inadvertent severing of telephone, fiber optic or CATV transmission cable, or damage to
sewer pipe is costly; RUPTURING OF GAS OR WATER LINES CAN CAUSE SERIOUS BODILY INJURY
AND/OR DEATH. COMING INTO CONTACT WITH BURIED POWER LINES CAN CAUSE SERIOUS BODILY
INJURY, SEVERE BURNS, AND/OR ELECTROCUTION. Call local utility companies or your local "One-
Call" number at least 48 hours before digging and have underground utilities marked.
DANGER: NEVER run engine inside building or enclosed area. Exhaust gases contain carbon
monoxide, an odorless and deadly poison.
DANGER: KEEP hands and feet away from rotating blades. Serious bodily injury will result.
CAUTION:
1. READ and understand this operators manual and the operators manual
for the engine. If one is not available, please call or write for a free replacement.

MAINTENANCE and LUBRICATION
DANGER: NEVER run engine inside building or enclosed area. Exhaust gases
contain carbon monoxide, an odorless and deadly poison.
Engines are shipped without oil or gasoline. Refer to MANUFACTURER'S INSTRUC-
TIONS for proper procedures and recommended fluids.
IMPORTANT DO NOT drop the machine off the back of a vehicle, this may cause
damage to the body and frame. Machines should always be lifted, ramped or
transported by a trailer.
LUBRICATING INSTRUCTIONS:
CHECK crankcase and gearbox oil level before each use.
CHANGE crankcase and gearbox oil as recommended by the manufacturer's instructions.
ADD grease to the pillow block bearings after every 100 hours of use.
CLEAN vertical frame posts and sleeves frequently to prevent binding. Do not use oil
base lubricants or grease. Silicone is recommended.
SHUT OFF ENGINE and disconnect spark plug wire to adjust, service, refuel or
clean the machine. Accidental engine starting is possible by rotating the cutter
wheel.
ALL nuts, fasteners and fittings must be kept properly torqued. After every 25 hours of
use the engine nuts and bolts should be checked and tightened, if necessary. Add lock-
tight to bolt threads.
AIR FILTER: The air filter needs to be cleaned every 10 hours. More often in dusty dry
conditions: Check engine owners manual for further instructions.
Attach a remote air filter with pre-cleaner in serious dusty conditions, this will add to the
engine life considerably.
CLUTCH: The slip clutch facings should be changed if the thickness is worn to 1/16" or
less, this will maintain the fast digging speed this type of unit can perform. Check every
20-25 hours of use.
ADJUSTMENT: Shoulder bolts must be kept tight. If the clutch wears to the point
where stopping the blades will not stall the engine within a few revolutions,
tension should be increased by adding a washer under each shoulder bolt, or by
replacing the clutch facings.

MAINTENANCE CONT...
V-BELT CARE: V-belts may be the item most overlooked during equipment mainte-
nance, but proper care and maintenance of V-belts and their sheaves (pulleys) can
yield great rewards. The nature of V-belts makes preventive maintenance relatively
easy. V-belts and sheaves wear gradually and usually give advance warning of
failure.
Nonetheless, it is important to recognize the warnings. All belts and sheaves will wear
as part of their lifes cycle. As wear occurs, the belts will ride lower in the grooves. A
worn belt is, in effect, longer than a new one.
V-belts grip by wedging in the pulley grooves. Belts that are too loose cause slippage,
loss of power, loss of speed and rapid wear to both the belt and the sheave. A howl or
squeal indicates that the belt is too loose or the load is too heavy.
ALIGNMENT AND TENSION: Check to be sure sheaves are properly aligned be-
cause misalignment can cause excessive wear to the belt sidewall. Unusual wear of
the belt outer cover is an indication of more serious mechanical trouble. V-belts are
designed to operate by making clean, dry surface contact with the sidewall of the
sheaves. Inspect belts periodically to assure that they are not contaminated with
grease or oil. Don't allow mud, rust or any other foreign matter to build up in sheave
grooves. Clean sheaves carefully with a wire brush.
SIGNS OF TROUBLE: Don't install new V-belts without carefully inspecting the
sheaves. Focus special attention on these conditions: ~ worn groove sidewalls ~ a
shiny sheave groove bottom ~ wobbling sheaves or ~ damaged sheaves. Sheave
sidewalls must be perfectly straight because the wedging action of the V-belt is
impaired and its gripping power is reduced when the walls are worn or dished out.
A shiny sheave groove bottom is an indication that the belt, sheave or both are badly
worn and the belt is bottoming in the groove. This condition may first be evident on
the smaller sheave.
Sheave wobble may be caused by ~ improper installation on the shaft ~ a worn/
damaged bushing ~ a worn/damaged sheave hub or by ~ a bent shaft. Any of these
conditions will cause early failure. The wobbling
sheave whips the belt
from side to side,
subjecting the belt to
lateral strain and causing
rapid wear to both the
sheave and belt. Vibration
is another indication of an
improperly installed or
damaged sheave; however,
vibration can also be caused by a damaged belt.

V-BELT CARE CONT...
Check the alignment of the sheaves. The drive and driven shafts should be parallel
both horizontally and vertically, and the centers of both sheaves should be in a straight
line. Although V-belts can tolerate minor misalignment (About 1/16 inch per 12 inches
of shaft center distance), close-to-perfect alignment will prolong belt life.
Set the belt take-up adjustment at its minimum position and place the new belt in the
correct position by hand. Never pry belts over the sheave with a screwdriver or other
hard object.
All V-belt drives must operate with correct belt tension to provide the optimum wedg-
ing action of the belt against the groove sidewalls. Allow a reasonable break in period
of a few hours, and then check for proper belt tension. New belts tend to elongate
slightly until they are seated in the sheave groove and initial stretch is removed from
the belt. Be sure to reinstall all protective guards and shields.
CUTTER HUB:
REMOVING THE CUTTER HUB: Should it ever be necessary to remove the
cutter hub, remove the three (3) cap screws and insert two (2) 1/4" - 20 cap screws into
the threaded holes in the bushing flange. Tighten the cap screws alternately and evenly
so the press against the shoulder of the cutter hub, "jacking" the bushing from the hub.
INSTALLING THE CUTTER HUB: To install the cutter hub, assemble the bush-
ing into the cutter hub so that the three (3) counter-bored holes in the bushing line up
with the three (3) threaded holes in the cutter hub. Insert the three (3) cap screws
through the counter-bored holes into the threaded holes and screw them in finger tight.
Slide the cutter hub and bushing on the shaft over the key. Locate the assembly so the
blades will clear the base and the guard. Tighten the cap screws in sequence around
the circle. Repeat until no further movement can be obtained (approx. 12 ft. lbs.).
BEARINGS:
The nylon bearing (clear collar) must be inserted in the blade with a slight inward
bulge. After locating the bearing in the collar of the blade, press the bulge to conform
to the contour of the cutter hub.

TRENCHER ASSEMBLY INSTRUCTIONS:
Remove the washers and pins that are on the front axles. Install two (2) front tires
with valve stem facing out. Re-install washers & pins. Install rear tire by inserting
axle bolt through wheel bearings and swivel. Install and tighten lock nut, leaving a
small amount of play in wheel bearings. Tire pressure should be 40 lbs. PSI.
Remove two (2) bolts from open neck of frame. Insert the push handle, re-install
bolts.
Attach hand crank and swivel end to manual actuator. Use hand crank to raise
shroud and engine all the way.
Follow engine manufacturers start up instructions. Fill crankcase with the recom-
mended oil. Add 30 wt. oil to the 6:1 gear reduction unit til it is 1/3 full.
Follow diagrams on page P-1.2 & 3 to install wear parts and the "Super Blade Plus" or
the "Super Extra Rock Blade" on P-4.
Double check all bolts and fasteners. Make sure the blade is properly installed and
the shoulder bolts are tightened.
BLADE/TEETH ASSEMBLY:
CAUTION: When removing or installing the blade or when making adjust
ments on the trencher, the spark plug must be disconnected to prevent acci
dental starting of the engine.
When determining which teeth are right hand or left hand, stand in the operating posi-
tion (standing behind the push handle and facing the direction of travel). The teeth
that are on the right hand side of the blade are the RIGHT TEETH. The teeth that are on
the left hand side of the blade are the LEFT TEETH.
To install new teeth, remove the two (2) shoulder bolts, die springs, friction plate,
clutch facings, and the blade. Remove the old teeth from the blade, install the new
teeth in the proper order, and remount the blade on the cutter hub.
The width of your trench is determined by the curvature of the tooth. You will have
straight teeth, curved in teeth (teeth that curve into the blade) and curved out teeth
(teeth that curve away from the blade).
For the KT200B Super Blade Plus (SBP) which has twelve (12) teeth, start placing your
teeth on the blade and keep a clock in mind. One o'clock, Two o'clock, etc. Follow
the diagram on page P-4 for this model. Standard cut is 2 inches.
The KT200B Super Xtra Rock Teeth (SXRT) only has four (4) "Super Xtra Rock Teeth"

TRENCHER OPERATING INSTRUCTIONS:
Put trencher in position.
Turn fuel on. Use choke when starting engine if necessary.
Allow engine to warm up for 2-3 minutes, then bring engine speed up with the
throttle.
Stand behind the push handle and lower trencher by turning the crank handle
counter-clockwise to required depth. Keep left hand on the handle for stability.
Push trencher forward to end of your trench.
NOTE: If in hard ground, roots and other problem areas, DO NOT attempt to
force machine. Allow the cutting blade do the cutting, over pushing may
cause the blade to bog-down.
INSTRUCT operator to back off immovable objects to eliminate early teeth breakage.
Raise the blade by turning crank handle clockwise until cutting blade is completely
out of the ground.
Stop the engine and turn the fuel off before moving the machine.
DO NOT use disc blade trenchers with missing teeth. If you do, this will
increase the possibility of engine vibration.

BELT REPLACEMENT INSTRUCTIONS
1. Reduce Belt Tension by loosening nuts on belt adjustment plate. (A)
2. Remove two nuts & bolts from pillow block bearing under the engine(B) and
remove spacer(C).
3. Slip the new belt over and under pillow block to the belt pulleys. Note: If
one belt needs replaced, all three belts need to be replaced at the same time
to assure maximum performance.
4. When belts are in place, replace spacer (C) and re-tighten belt adjustment
nuts until there is little slack in the belts (D).
5. If the digger blade slips when trenching, add more tension to the belts.
However, over tensioning will cause premature belt and/or bearing failure.
