Introduction
The Optima Steamer represents the future of environmentally friendly and effective cleaning. Safe,
durable and easy to use, the Optima will support your cleaning operations for many years to come.
Intended Applications
The Optima Steamer is designed for cleaning surfaces capable of handling steam jet pressure of
up to 8.5 bar (123.2 psi) and maximum temperatures reaching at 135℃ (275℉).
The Optima Steamer is capable of cleaning various surfaces including, but not limited to machinery
/ parts, vehicle exteriors and interiors, engine compartment, glass, metal surfaces, windows, wheel
wells, vents, kitchenware, remove weeds and much more while simultaneously sanitizing and
deodorizing with very little water consumption.
Safety Precautions
Before operating the Optima for the first time, read the manual completely.
The manufacturer and distributors are not liable for the mechanical troubles, property
damage, or personal injury caused by the operator(s) unfamiliarity with the manual’s
instructions.
• With regards to the steam vessel, use only water and the manufacturer’s recommended steam
vessel cleansing solution. Do not put any other chemicals or detergents into the water tank or
steam vessel.
• Do not use distilled water or filtered water under 15 ppm
• “Soft” water is recommended. Otherwise, use only clean tap water with anti-scaling solution.
• Use only clean diesel.
• Provide adequate electrical power requirements accordingly to the specifications.
• Make sure that all the switches on the machine are off before plugging the machine into an
electrical outlet.
• If an extension cord is used, make sure it is constructed waterproof and of proper diameter
based on the cord length and required electrical specifications.
• Turn off the POWER (EMERGENCY STOP) and STEAM switches when refilling the fuel tank.
• Turn off and unplug the machine from its power source and allow the Optima Steamer to cool
down before carryi ng out any maintenance.
• Use only hoses, steam-guns and all other accessories recommended by the manufacturer. Use
manufacturer approved spare parts only.
• Use and store the Optima on a leveled up surface only.
• Do not use the machine in rain or snow outdoors. The Optima Steamer is not weather-pro of or
water-proof.
• Never leave the machine unattended while in use.
• Never store the machine below 0℃ (32℉) or extremely cold weather condition.
• In cold climates, do not allow water to sit when the Optima is not in use. Do not operate the
machine if any parts are frozen or suspected of being frozen.
(See “Freeze Prevention on page13)
• Do not use the Optima if any part, power cord, safety device, hose or spray gun is visually
damaged or suspected of being damaged.

• Use proper ear, eye and hand protection when operating the Optima. Noise can be generated
from steam pressure and it can be reach 95 decibels (dB).
• Do not use the machine within the range of people who are not wearing any protective gears.
• Do not direct the steam jet spray, aim or discharge at itself, live electricity, people or animals.
• The machine is not to be used by children or persons with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction.
• Keep the Optima away from children and animals at all times.
• Children should be supervised to ensure that they do not play with the machine.
• Never disable a sensor in order to bypass an alarm.
• To provide continual pr otection against risk of the electric shock, connect properly to grounded
outlets only.
• The exhaust is very hot. Take precautions when operating the Optima within a confined space
or indoors.
• Provide proper ventilation for Optima Steamer. The Optima DM(DM), DM(DMF), DM(DS) are
oil-heated appliances.
