The DiamaPro DPBRN27-X+ is a 27-inch propane burnisher designed for floor care, offering efficient operation and maintenance for various applications.

Function Description:

The DPBRN27-X+ is a powerful propane-powered burnisher used for polishing and maintaining floors. It is designed to provide high-quality finishes on a variety of floor types. The machine's engine exhaust contains carbon monoxide, an odorless and deadly gas, necessitating strict adherence to safety instructions regarding ventilation and operation. Propane, being highly flammable, also requires careful handling as outlined in the manual. The burnisher features rotating pads and parts under the machine frame, which can cause serious injury if not handled properly, emphasizing the need to keep hands and feet away during operation.

Important Technical Specifications:

The burnisher is powered by a propane engine, with specific details on the engine model (DiamaPro OHV) and related components provided in the illustrated parts lists. Key battery specifications include:

Model: HJTZ5S-30-GFP
Voltage (V): 12.8
Capacity (Ah): 3
Weight: 0.7 kg / 1.5 lb
Charging Current: 0.5A to 15A
Charging Voltage: 14.4 ± 0.5 V
Cold Cranking Amps: 180
Cycle Life: ≥1000 The oil capacity for the engine is approximately 2.0 liters. Recommended spark plug gap is 0.6-0.8mm, using F7TRC (NHSP) or equivalent.

Usage Features:

Handle Adjustment: The handle can be adjusted to various heights to accommodate different operators and preferences. This involves loosening a knob, pivoting the handle to the desired position, and then tightening the knob.
Wheel Position Adjustment: The position of the two front wheels significantly affects the machine's performance, including pad pressure, forward propulsion, and machine torque. Adjustments can be made to increase or decrease pad pressure, increase or decrease forward propulsion, and increase or decrease machine torque. This is achieved by moving both wheels rearward/forward, offsetting them for height differences, or moving them down/up.
Starting the Engine: The process involves slowly opening the main service valve on the propane cylinder, setting the throttle to idle, rocking the machine back on its rear casters to lift the pad off the floor, and turning the ignition switch to "Start." A warm-up period of 30 seconds is recommended before applying full load.
Stopping the Engine: For a normal stop, set the throttle to idle, close the service valve on the propane cylinder, allow remaining propane to be consumed, turn the key switch off, and disconnect the fuel line. For an immediate stop, turn the key switch off, close the service valve, and disconnect the fuel line.
Propane Cylinder Use: Propane cylinders must be designed for vapor withdrawal and installed in the correct orientation (horizontal or vertical, as indicated by a "THIS SIDE UP" label). Only HD-5 grade propane should be used. Cylinders should be filled vertically to 80% capacity by trained personnel, ensuring the fixed liquid level gauge is opened during filling and closed once liquid propane appears.
Environmental Conditions: Operation in low temperatures can lead to difficult cold starting, while very high temperatures can cause difficult hot starting due to fuel evaporation. Altitude also affects engine power, requiring reduced load at higher altitudes.
Work Considerations: Different types of work, such as floor stripping (slow movement) versus burnishing (high movement), present varying risks of CO exposure. Small Effective Operating Zones (concentrated activity) increase CO risk, necessitating the use of fans for air mixing and stirring to reduce concentrations.

Maintenance Features:

The manual provides a comprehensive maintenance schedule:

Daily/Every 5 Hours: Check engine oil level, check for loose hardware, check for fuel or oil leakage, check/clean intake air filter, check/clean bonnet filter, check, clean, and/or replace dust bag, and check pad.
Every 25 Hours (or more frequently if operating under heavy load or in hot weather): Change oil.
Every 50 Hours/Every Season: Check shroud & shroud seal, check engine mounts.
Every 100 Hours: Check belt for wear or slippage, check pulleys, drive shaft, and bearings, check wheels & bearings, change oil filter, check spark plug, fuel filter check.
Every 200 Hours: Replace spark plug, replace air cleaner primary element.
Every 500 Hours: Replace air cleaner secondary element.
Overall Checkup: An overall checkup at an authorized service center is recommended every 200 hours.

Specific maintenance procedures include:

Oil Change: Drain warm oil, clean around the filler cap, unscrew the cap with dipstick, collect old oil, refit the drain plug, fill with fresh oil to the "MAX" mark, and tighten the filler cap.
Air Filter Maintenance: Clean debris from the air filter cap and rain cover, open clips, gently shake and tap the cartridge to remove dust, and blow from the inside with compressed air. Do not use water, petrol, or detergents. Clean the inside of the filter housing, reinstall elements, and secure the cover.
Spark Plug Service: Remove the spark plug, clean electrodes with a metal brush, check the gap (0.6-0.8mm) with a thickness gauge, and install/tighten. Replace if electrodes are burnt or porcelain is damaged.
Dust Collection Maintenance: If equipped, remove the dust bag, unzip, empty contents outside, and reinstall. The bag is functional for 20-30 cycles before replacement.
Battery Maintenance: The onboard charging system charges the battery during normal use. For offline charging, disconnect the battery, connect charger clamps (red to positive, black to negative), set output voltage and amperage (12V, 0.5-15A), plug in for at least 8 hours, then disconnect and reinstall.
Long Storage (over 30 days): Empty the fuel tank, remove the spark plug, pour 3 cl of clean engine oil into the spark plug hole, run the starter motor briefly, and replace the spark plug without connecting the cable cap. Store the machine indoors in a climate-controlled, low-humidity location with the propane tank removed and battery cables disconnected to prevent drain.

Emission Control Warranty:

The emission control system is warranted for 1000 hours (JLHRS.9992EM family) and 500 hours (JLHRS.6032EM family). The warranty covers parts like the carburetor, fuel-injection system, ignition system, catalytic converter, fuel tanks, fuel lines, fuel caps, valves, canisters, filters, vapor hoses, clamps, connectors, and other associated emission-related components. The warranty is voided by abuse, neglect, or improper maintenance.
