flammable liquids.  
CauTion  
„ neveR touch the hot exhaust manifold,  
muffler or cylinder.Allow these parts to cool  
before servicing equipment.  
„ do noT fill the fuel tank while the engine is running  
or hot.  
„ do noT overfill tank, since spilled fuel could ignite if it  
comes into contact with hot engine parts or sparks from  
the ignition system.  
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.  
„ Store fuel in appropriate containers, in well-ventilated

general inFOrMatiOn  
deFiniTion oF TaMping RaMMeR  
CauTion  
The Multiquip MTX60HF 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.  
Before starting operation check the lifting  
handle to:  
1. Make sure that there is no damage on the bolts.  
2. Make sure that there is no crack or breakage on  
handle.  
The impact force of the MTX60HF levels and uniformly  
compacts voids between soil particles to increase dry  
density.  
3. Make sure that there is no fissure on the surface.  
If there is any abnormality or damage, replace  
with new one.  
Circular motion is converted to create impact force.  
The MTX60HF tamping rammer develops a powerful  
compacting force at the foot of the rammer. To maintain  
optimum performance, proper operation and service are  
essential.  
For operation:  
This handle is to be used to lift up the shoe part of  
the machine with the body laid down on the ground  
or truck bed.  
ConsTRuCTion oF TaMping RaMMeR  
1. Use proper lifting techniques to avoid back injury.  
This handle is for manual lifting only.  
The MTX60HF is equipped with an air cooled, four- cycle  
gasoline engine. Transmission of the power takes place  
by increasing the engine speed to engage the centrifugal  
clutch.  
2. Do not use this handle as a rammer lift point. Use  
the lifting point on the top of the machine.  
3. Do not move the rammer with the lifting handle  
and the front rollers more than 16 feet (5 meters).  
RaMMeR geaRboX and spRing CylindeR  
The MTX60HF 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 MTX60HF Tamping Rammer identify  
and understand the function of the controls.

Figure 1. MTX60HF Rammer  
Figure 1 shows the location of the controls and components  
for the MTX60HF Tamping Rammer.The functions of each  
control is described below:  
8. Foot — Laminated wood with tempered steel plate for  
superior shock absorption.  
9. Fuel Tank — Holds the fuel for the unit (up to 3.2  
quarts).  
1. Combination (Throttle) lever — Used to adjust  
engine speed (rpm). Move lever forward (SLOW) to  
reduce engine speed, move lever back toward operator  
(FAST) to increase speed.Always operate the rammer  
at full speed (rpm).  
10. Muffler — reduces the noise of the engine when  
running.  
11. engine — this unit uses a Honda GX100UKRB5  
gasoline engine.  
2. Handle To operate rammer, GRIP handle assembly  
firmly on both sides.  
12. oil gauge (sight glass) — Indicates the level of oil in  
the oil bath reservoir.  
3. Fuel Tank Cap — Remove this cap to add unleaded  
gasoline to the fuel tank. Make sure cap is tightened  
securely. DO NOT over fill.  
13. drain valve — Open this valve to remove oil from the  
bellows.  
WaRning  
4. Hook — Used to lift rammer for transporting.  
Adding fuel to the tank should be  
accomplished only when the engine is  
stopped and has had an opportunity to  
cool down. In the event of a fuel spill, DO  
NOT attempt to start the engine until the  
fuel residue has been completely wiped up, and the  
area surrounding the engine is dry.  
5. air Cleaner Cover — Protects the air cleaner which  
prevents dirt and other debris from entering the engine.  
6. Roller — Allows rammer to be moved around easily  
by rolling the unit.  
7. bellows — Reservoir for oil bath.

BasiC engine  
Figure 2. Honda GX100 Engine  
4. Muffler — Used to reduce noise and emissions.  
The engine (Figure 2) must be checked for proper lubri-  
cation and filled with fuel prior to operation. Refer to the  
engine manufacturer's manual for detailed operation and  
service information.  
5. dipstick/oil Filler Cap — Remove this cap to  
determine if the engine oil is low. Add oil through this  
filler port as recommended in Table 3.  
1. Choke lever — Normally used in starting the engine  
in cold weather conditions. In cold weather, turn  
the choke lever to the fully closed position. In warm  
weather, set the choke lever halfway or completely  
open.  
6. oil drain plug — Remove this plug to remove oil from  
the engine's crankcase.  
WaRning  
Engine components can generate  
extreme heat. To prevent burns, do  
noT touch these areas while the  
engine is running or immediately  
after operating. neveR operate the  
engine with the muffler removed.  
2. spark plug — Provides spark to the ignition system.  
Set spark plug gap to 0.024 - 0.028 inch (0.6 - 0.7 mm).  
Clean spark plug once a week.  
3. Recoil starter (pull rope) — Manual-starting method.  
Pull the starter grip until resistance is felt, then pull  
briskly and smoothly.  
NOTICE  
Operating the engine without an air filter, with a  
damaged air filter, or a filter in need of replacement  
will allow dirt to enter the engine, causing rapid engine  
wear.
