MT-84F — OPERATION AND SAFETY DECALS

Machine Safety Decals

The MQ Mikasa MT-84F tamping rammer is equipped with a number of safety decals. These decals are provided for operator safety
and maintenance information. Figures 1 and 1A below and preceding page illustrates these decals as they appear on the machine.
Should any of these decals become unreadable, replacements can be obtained from your dealer.

MT-84F — GENERAL INFORMATION

Definition of Tamping Rammer

The Mikasa MT-84F tamping rammer is a powerful compacting
tool capable of applying a tremendous force in consecutive
impacts to a soil surface. Its applications include soil compacting
for road, embankments and reservoirs as well as backfilling for
gas pipelines, water pipelines and cable installation work.

The impact force of the MT-84F levels and uniformly compacts
voids between soil particles to increase dry density.

Circular motion is converted to create impact force. The MT-84F
tamping rammer develops a powerful compacting force at the
foot of the rammer. To maintain optimum performance, proper
operation and service are essential.

Construction of Tamping Rammer

The Mikasa MT-84F is equipped with an air cooled, two cycle
gasoline engine. Transmission of the power takes place by
increasing the engine speed to engage the centrifugal clutch.

Rammer Gearbox and Spring Cylinder

The Mikasa MT-84F uses an oil bath lubrication system. Always
check the oil level through the oil level sight glass at the rear of
the tamper foot.

Controls

Before starting the MT-84F Tamping Rammer, identify and
understand the function of the controls. See Figure 2.

MT-84F — OPERATION

This section is intended to assist the operator with the initial
start-up of the MT-84F Tamping Rammer. It extremely important
that this section be read carefully before attempting to operate
the rammer.

DO NOT use your rammer until this section is thoroughly
understood.

CAUTICAUTI

CAUTION

CAUTICAUTI

Failure to understand the operation of the MT-84F Tamping
Rammer could result in severe damage to the trowel or
personal injury.

Rammer Gearbox and Spring Cylinder Oil Bath

This unit uses an oil bath lubrication system. Perform the following:

1. Check the oil level through the oil level sight glass (Figure 4)
at the rear of the tamper foot.

Fuel Check

1. Check the fuel level in the fuel tank. If the fuel level is low, fill
the fuel tank (Figure 5) with clean unleaded gasoline.

Engine Oil Check

1. To check the engine oil level, place the rammer on
secure level ground with the engine stopped.

2. Remove the filler dipstick from the engine oil filler hole
(Figure 6) and wipe it clean.

Figure 5. Fuel Tank

3. Insert and remove the dipstick without screwing it into the

Figure 4. Foot Housing Sight Glass

2. If oil is not visible, add 10W-30 motor oil into the oil fill plug
opening (Figure 2). The bath contains approximately 1.7
pints (800 cc.)

NOTE

The oil bath level should be kept
at the half way point of the sight
glass.

CAUTION

CAUTICAUTI

Make sure that the throttle lever is moved to the FULL OPEN
position. Operating the rammer at less than full speeds can
result in damage to the clutch springs or foot

2. The MT-84F tamping rammer is designed to run at 4,000 rpm.
At optimum rpm the foot hits at the rate of 660~700 impacts
per minute. Increasing throttle speed past factory set rpm
does not increase impacts and may damage unit. The MT­84F is designed to advance while tamping. For faster
advance, pull back slightly on the handle so that rear of foot
contacts soil first.
