FEATURE
The KPT 36 and the KPT 48 Walk Behind Power Trowels can be used in surface finishing of concrete road, terrace, boatyard, airport and floor etc.
Deadman switch design pr ovide safe. A sophisticated system to protect the operator from an out-of-control spinning handle. When the operator is using a walk-behind power trowel and let go of the safety sensor detects the motion of the handle and stops the engine before the handle reaches a 45-degree ro tation. The handle can be adjusted due to the stature of operator, and it offers maximum control and comfort for the operation. The alloy blades which have get heat treatment are worn well. Low center of gravity provides workers with saf e and stable operation.

SAFETY PRECAUTIONS
3
1. Before starting operation, the operator has to check that all control and safety devices function properly.
2. Always keep unauthorized, inexperienced, untrained people away from this machine.
3. Rotating and moving parts will cause injury if contacted. Make sure guards are in place. Keep hands and feet away
from moving parts.
4. The engine must always be stopped before attempting any repair or adjustments. Ignition switch should be off.
5. To avoid slipping and loss of control when starting the trowel, the operator should maintain good footing. It is
recommended that the operator wear safety shoes for added protection.
6. Be careful when working around pipes or ducts protruding from the floor or slab edges. If the trowel blades hit such
obstacles, damage to the machine or possible operator injury may result.
7. When starting the machine, do not exceed 1/3 throttle position. A higher setting may cause the Centrifugal clutch to
engage and the handle to rotate.
8. Be careful not to come in contact with the muffler when the engine is hot, serious burns may result!
9. Over time, the blades will form a sharp edge. Be careful when handling the old blades.
10. Gasoline is extremely flammable, and gasoline vapor can explode. Refuel outdoors, in a well-ventilated area, and keep
other flames and sparks away.
11. Do not fill the fuel tank completely. After refueling, tighten the fuel tank cap securely.
12. Before beginning your preoperational checks, be sure the engine is level and the engine switch is in the OFF. The max.
gradient of 20° must not be exceeded when the engine working.
13. Don’t allow children to operate the engine. Keep children and pets away from the area of operation.
14. After each use your machine should be cleaned to remove any dust and debris from the undercarriage and
surrounding components.
15. When the machine start working you should be check the clutch whether or not wear and tear. If the clutch will have
3/4 worn and torn, you must change new clutch-ring.
16. Check that all shields and covers are in place, and all nuts, bolts, and screw are tightened when the machine working.
Make sure put the cable while the machine working.
MAINTENANCE RECORD
Due to the nature and environment of use, Walk-behind Power Trowels could be exposed to severe operating conditions. Some general maintenance guidelines will extend the useful life of your trowel.
1. The initial service for your trowel should be performed after 25 hours of use, at which time your mechanic
(or authorized repair shop) should complete all of the recommended checks in the schedule below. The chart is handy for keeping a record of the maintenance performed and the parts used for servicing your trowel.
2. Regular service according to the schedule below will prolong the life of the Walk-behind Power Trowel and prevent
expensive repairs.
3. Keeping your Walk-behind Power Trowel clean and free from debris is the single most important regular maintenance
operation, over and above the checks in the service schedule above, that can be performed. After each use your Walk behind Power Trowel should be cleaned to remove any dust and debris from the undercarriage and surrounding components. Use of a power washer will make clean up quick and easy, especially if a non-stick coating was applied prior to use.
4. In the Service Schedule below, items that should be checked, replaced or adjusted are indicated by "o" in the
column. Not all Walk-behind Power Trowel models include the same features and options and as such not all service operations may have to be performed. For ease of recording place a checkmark (√) through the "o" when the item is complete. If an item is not required or not complete place an "×" through the "x" in the box.
CAUTIONS! Over time, if the blades will have 3/4 worn and torn, you must change new trowel blades.

adjusted due to the stature of operator through pitch control assembly. Dead man switch designs provide safe and stable operation. Holding the deadman lever before start the engine, and loosening deadman lever the machine will stop working.
OPERATION (Floating)
When the slab has set sufficiently firm that the operator’s footprint leaves a very slight depression on the surface of the slab, it is ready for the floating operation.
Guiding the machine on the slab is very simple; a slight upward lift of the handle causes the machine to travel to the left. Holding the handle in the neutral position, will slowly cause the machine to spin in one spot. Slight downward pressure on the handle causes the machine to the travel to the right. Best results are obtained by covering approximately 4” on each turn. In other words, let the machine move right or left, backwards or forwards, approximately 4” with each revolution of the trowels. To fill a hole or cut down hump, move the unit back and forth over the problem area.
Under normal operating conditions the machine should cover as much as 1000 sq. ft. in about 15 minutes. It is recommended that a slight tension on the trowel control cable, (but not a definite tilt), during the floating operation will cause the machine to operate much smoother. After the floated slab has set sufficiently, it is ready for the finishing operation.
CAUTION!
operation is complete.
Do not let the machine stand in one spot on the soft cement. Lift from the slab when the floating

OPERATION (Finishing)
When starting the finishing operation, never set the trowels up over 1/4" pitch. After the floating operation, the first thing to do is to remove the floating disc from the blades. Clean the blades, spider plate and disc from cement paste collected during the floating operation. Increase the blade pitch up to a maximum of 1 cm for the first finishing operation and then continue to increase the pitch on the following finishing operations. Continue the finishing passes until you obtain the desired floor finish. The time required between each finishing pass is again dependent on the weather conditions and water content of the concrete etc. If some areas of the concrete set/harden too fast you may apply a small amount of water using a hand brush as an aid to achieving the finish.
STARTING & STOPPING PROCEDURE
1. Before operation checks
a.
Check the oil level: Before beginning your preoperational checks, be sure the engine is level and the engine switch
is in the OFF. Remove the filler cap/dipstick and wipe it clean. Insert and remove the dipstick without screwing it into the filler hole. Check the oil level shown on the dipstick. If the oil level is low, remove the oil filler cap, and fill to the upper limit mark on the dipstick with recommended oil. Screw in the filler cap/dipstick securely. SAE 10W-30 is recommended for general use. The engine is certified to operate on unleaded gasoline with a research octane rating of 90 or higher. Unleaded gasoline produces fewer engine and spark plug deposits and extends exhaust system life. Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting dirt or water in the fuel tank.
b.
Check air filter: Remove the air cleaner cover and inspect the filter. Clean or replace dirty filter elements. Always replace damaged filter elements. If equipped with an oil-bath air cleaner, also check the oil level.
Notice!
Running the engine with a low oil level can cause engine damage.
2. Start engine/Stopping engine procedure
Move the fuel valve lever to the ON position.
a.
b. Move the choke lever to the CLOSE position. If the engine is warm or the air temperature is high, move the control lever away from the OPEN position as soon as the engine starts.
5
c. Move the throttle lever away from the SLOW position, about 1/3 of the way to toward the FAST position.
d. Turn the engine switch to the ON position.
6
e. Pull the starter grip lightly until you feel resistance, then pull briskly. Return the starter grip gently.
CAUTION!
Do not allow the starter grip to snap back against the engine. Return it gently to prevent damage to the starter.
3. Stopping the engine
a.
Move the throttle lever to the SLOW position.
f. If the chock lever or chock rod (applicable types) has been moved to the CLOSED position to start the engine, gradually move it to the OPEN position as the engine warms up.
b. Turn the engine switch to the OFF position.
c. Turn the fuel valve lever to the OFF position.
4. Setting engine speed
Position the throttle lever the desired engine speed.
