DiamaPro Systems DPBRN27-X+ - Stopping Engine

WARNING: Substantial damage to the oor, the machine, or
personnel may result if the machine is operated with the pad o󰀨
center, damaged or missing. Do not operate the machine if the
pad is o󰀨 center, damaged or missing.
WARNING: Operating an engine that has loose parts could result
in injury or property damage. DO NOT operate this engine if there
are loose parts. Inspect the engine for loose parts frequently. This
will promote safe operation and a long engine life.
WARNING: Vibration from machinery may cause numbness or
tingling of the ngers in certain people. Smoking, dampness, diet,
and heredity may contribute to the symptoms. Wearing warm
clothing, gloves, exercising and refraining from smoking can re-
duce the e󰀨ects of vibration. If the symptoms still persist, discon-
tinue operation of the machine.
CAUTION: OVERHEATING is a major cause of engine failure.
Keep the engine clean and free of debris build up.
CAUTION: Low oil levels and dirty oil account for most of the other
failures. Follow the engine manual’s recommended oil change
schedule.
1. Check engine oil level according to Engine Operator Manual
2. Ensure propane cylinder has been properly lled according to section
“Filling Propane Cylinders”
3. Check for any sign of wear or damage such as cracks, corrosion, punc-
tures, etc. to the fuel system including propane cylinder, fuel hoses,
ttings, regulator, carburetor, and electrical components.
4. Ensure main service valve on propane cylinder is closed (turned
clockwise).
5. Screw the REGO tting of the high-pressure propane hose onto the
cylinder service valve and hand tighten. This connection MUST be tight
and secure and fully seated to function.
6. Ensure propane tank is secured with clamping strap
7. Ensure handle is secure and at a comfortable position
8. Ensure all machine parts (belt, pad, handle, wheels, etc.) are in place
and secure.
9. Ensure the pad is at least 1/3 inch thick, and that the pad holder is tight.
10. Ensure the pad driver is secure to the drive shaft.
11. Ensure the battery cable is connected.
WARNING: Before attempting to start engine, become familiar
with all controls of the machine.
1. Slowly open the main service valve on propane cylinder to the fully
open position.
2. Set throttle to Idle position.
3. Ensure machine is rocked back on its rear casters, so the pad is not in
contact with the oor.
4. Turn Ignition Switch to “Start”, which will engage starter. Allow cranking
for a maximum of 6 seconds or until the engine res.
If engine fails to re on the rst attempt, repeat this step. It will likely re
on the second attempt due to internal fuel priming.
CAUTION: Serious starter damage will result if starter is engaged
for more than 6 seconds, and will void warranty.
5. Once engine has started, slowly increase throttle. Allow for a warm-up
period for 30 Seconds before applying full load to the engine.
Note: If the engine fails to start, see the Troubleshooting Guide.
2. OPERATION
2.1. Preparation
2.2. Starting the Engine
3. STOPPING ENGINE
Normal Stop
Follow these stopping procedures under normal use, including when the
engine will be stored or transported:
1. Set throttle to Idle position.
2. Close the service valve on propane cylinder (turn clockwise fully).
3. Allow the remaining propane in the regulator and fuel hose to be
consumed by engine, until engine stops.
4. Turn engine key switch to o󰀨.
5. Disconnect fuel line from propane cylinder.
6. If storing or transporting the machine, follow instructions in section
“STORING & TRANSPORTING PROPANE CYLINDERS”
Immediate Stop
Follow these stopping procedures only when an immediate stop is
required:
1. Turn engine key switch to o󰀨.
2. Close the service valve on propane cylinder (turn clockwise fully).
3. Disconnect fuel line from propane cylinder.
The handle on this machine can be adjusted to several heights, to accom-
modate di󰀨erent sized operators and di󰀨erent operator preferences.
To adjust the handle:
1. Stop the engine.
2. Loosen the Handle Adjustment Knob, until the Handle is allowed to pivot
freely. Note: Do not fully remove this knob.
3. Adjust the Handle to desired position.
4. Tighten the Handle Adjustment Knob.
The position of the two front wheels has signicant a󰀨ect on the perfor-
mance and handling of the machine, including:
Pad pressure = The amount of force the pad has against the oor
Forward propulsion = The feeling of forward pull or drive caused by pad
friction
Machine torque = The feeling that the machine wants to constantly turn,
usually toward the left
When your machine was assembled, the wheels were installed in posi-
tions determined to allow for best performance under most conditions.
However, depending on oor type, oor nish type, pad type, and
operator preference, these wheel positions can be changed to a󰀨ect
machine performance.
For the purpose of clarity, the following terms will be used in this section:
Forward = closer to the front of the machine
Rearward = closer to the rear of the machine
Up = closer to the sky
Down = closer to the ground
Left = the left side when viewed from the Operator’s position
Right = the right side when viewed from the Operator’s position
Through wheel adjustment, the following changes can be made to the
machine performance:
To change the wheel position:
1. Stop the engine.
2. Adjust handle position to highest position and rock machine back, until
handle grips are resting on ground.
3.1. Handle Adjustment
4. WHEEL POSITION ADJUSTMENT
DESIRED CHANGE
Increase pad pressure
Decrease pad pressure
Increase forward propulsion
Decrease forward propulsion
Increase machine torque
Decrease machine torque
ADJUSTMENT TO MAKE
Move both wheels (left and right) Rearward
Move both wheels (left and right) Forward
O󰀨set the two wheels, so the right wheel is
Higher (more “up”) than left
Align the two wheels, so the left and right
wheel are the same height
Move both wheels (left and right) Down
Move both wheels (left and right) Up
