SAFETY INFORMATION
ROLLER SAFETY
DANGER
NEVER operate the equipment in an explosive
atmosphere or near combustible materials.An
explosion or fire could result causing severe
bodily harm or even death.
WARNING
NEVER disconnect any emergency or safety devices.
These devices are intended for operator safety.
Disconnection of these devices can cause severe injury,
bodily harm or even death. Disconnection of any of these
devices will void all warranties.
CAUTION
NEVER lubricate components or attempt service on a
running machine.
Never leave the roller unattended with the engine
running. Turn off engine.
Use chock blocks when parking roller on a grade.
Use extreme care when operating near obstructions, on
slippery surfaces, grades, and slide slopes.
When reversing, particularly on the edges and banks
of ditches, as well as in front of obstaces, the operator
must stay in a standing position at a safe distance from
the machine.
When operating near any house/building or pipelines,
always check the effect of machine vibration. Stop work
if necessary.
DO NOT operate the roller with the covers open.
ALWAYS keep the machine away from other personnel
and obstacles. Always keep immediate are free of
bystanders.
NOTICE
ALWAYS keep the machine in proper running condition.
Fix damage to machine and replace any broken parts
immediately.
DO NOT use worn-out hoses or couplings. Inspect daily.
ALWAYS store equipment properly when it is not being
used. Equipment should be stored in a clean, dry location
out of the reach of children and unauthorized personnel.
ENGINE SAFETY
DANGER
The engine fuel exhaust gases contain poisonous carbon
monoxide. This gas is colorless and odorless, and can
cause death if inhaled.
The engine of this equipment requires an adequate
free flow of cooling air. NEVER operate this equipment
in any enclosed or narrow
area where free flow of the
air is restricted. If the air
flow is restricted it will cause
injury to people and property
and serious damage to the
equipment or engine.
WARNING

compartment when engine is running.
NEVER operate the engine with heat shields or
guards removed.
Keep fingers, hands hair and clothing away
from all moving parts to prevent injury.
DO NOT remove the engine oil drain plug
while the engine is hot. Hot oil will gush out of the oil
tank and severely scald any persons in the general area
of the roller.
CAUTION
NEVER touch the hot exhaust manifold,
muffler or cylinder. Allow these parts to cool
before servicing equipment.
Always turn the engine off before performing maintenance.

SAFETY INFORMATION
NOTICE
NEVER run engine without an air filter or with a dirty air
filter. Severe engine damage may occur. Service air filter
frequently to prevent engine malfunction.
NEVER tamper with the factory settings
of the engine or engine governor. Damage
to the engine or equipment can result
if operating in speed ranges above the
maximum allowable.
NEVER tip the engine to extreme angles during lifting as
it may cause oil to gravitate into the cylinder head, making
the engine start difficult.
FUEL SAFETY
DANGER
DO NOT add fuel to equipment if it is placed inside truck
bed with plastic liner. Possibility exists of explosion or
fire due to static electricity.
DO NOT start the engine near spilled fuel or combustible
fluids. Diesel fuel is extremely flammable and its vapors
can cause an explosion if ignited.
ALWAYS refuel in a well-ventilated area, away from
sparks and open flames.
ALWAYS use extreme caution when working with
flammable liquids.
DO NOT fill the fuel tank while the engine is running

GENERAL INFORMATION
The Mikasa Model MRH800DS2 is a powerful compacting
tool capable of applying tremendous force in consecutive
impacts to a soil surface. Its applications include soil
compacting for backfilling for gas pipelines, water pipelines
and cable installation work.
The impact force of the MRH800DS2 levels and uniformly
compacts voids between soil particles to increase dry
density.
Features include:
Hydraulic transmission to allow speed change without
gear shifting.
Deadman device which when pressed or hit will cause
the travel lever to return to neutral position bringing the
machine to a stop.
A horn to warn of machine’s approach.
Non-corrosive water tank for the sprinkler system with
a capacity of more than 10 gallons.
Lifting hook to transport machine.
Front bumper and working light.
Narrow profile with less than one inch wall clearance.
Narrower width allows access to tighter areas. No
exposed hydraulic hoses.
Oil bath lubricated bearings and external vibration for
less servicing and more dependability.
Front and rear drum scrapers.
Drum sprinkler system controls located near the operator.
Easy access to hydraulic components and hydraulic filter.
