Proposition 65 Warning:
Engine exhaust and some of its constituents, and some dust created by power
sanding, sawing, grinding, drilling and other construction activities contains
chemicals known to the State of California to cause cancer, birth defects and
other reproductive harm.
Some examples of these chemicals are:
Lead and lead-based paint.
Crystalline silica from bricks.
Cement and other masonry products.
Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do this type
of work. To reduce your exposure to these chemicals: ALWAYS work in a well
ventilated area, and work with approved safety equipment, such as dust mask
that are specially designed to filter out microscopic particles.

4. RULES FOR CONDUCTING SERVICE WORK
1. In order to avoid deficient reassembly, know normal status of installation before removing or
disassembling any part. Level check or replacement of vibrator oil should be carried out on level
ground.
2. Each time disassembly is made involving oil seal, gasket, packing, o-ring, lock washer or the like, be
sure to replace them with new ones.
3. Mating surfaces of vibrator case and compaction plate should be sealed with liquid gasket (Clean
and de-grease the mating surfaces thoroughly).
4. For tightening bolt and nut, use the specified standard torque andbonding agent (Loctite or the
like). For such bolt and nut that are not specified, see Table of Tightening Torque. (Before
coating with Loctite, clean the screws thoroughly.)
Note) All the screwsin use with this machine are right handed.

5. Disassembly work should be conducted where it is free from dust.
6. Where bonding agent such as Loctite has been in use and screw is hard to loosen, heat it with torch
lamp or the like. Such heated bolt must be replaced with new one, which is of high-tension type as
specified.
7. Use proper tool in proper manner.

5-1 OPEARTION SYSTEM (MVH-R60)
Disassembly
1. Removing two bolts (51) causes throttle body (37)
and throttle lever (39) to come off as an assembly.
Removing the double nut (46, 47) causes the
throttle lever to come off the throttle body.For
removing throttle lever off the machine, remove
the throttle wire (50) which has been screwed
down to the engine.
2. Removing bolt (18) causes the travel lever (17) to
come off hand pump (16).
3. Remove hydraulic hose (26) from the elbow of
vibrator shown in the drawing of disassembled
vibrator.
4. Removing four bolts (28) shown in the drawing allows to remove the handle (1) from base.
Reassembly:
Reassemble the system with its disassembly procedure reversed while observing below:
1. For installing the handle assembly (1) to the base, first have the four bolts (28) tightened only
lightly which are fixing the handle bracket (R) and (L) (26, 27) in the developed drawing, and after
adjusting resistance in handle operation by means of double nut (12), retighten them securely.
2. Have the throttle lever resistance adjusted with double nut (46, 47) before fixing the throttle lever
(39) with socket head set screw (45). The nut tightening torque is 120kgf-cm.
3. Set rpm for high speed side of engine (See Table 1) should be adjusted by means of engine set screw
on the engine side.
5. DISASSEMBLING/REASSEMBLING THE MVH-R60~150:
！Note
: Whenever hydraulic hose has been disconnected, apply blank plug to it for prevention of
any dust from entering.
Remove hydraulic hose clamp (27), its retainer bolt (28) and nut (29). Removing two
bolts (21) and nuts (22) allows to remove grip (25) and hand pump (16) from handle (1).

For VIBRO-COMPACTOR MODEL MVR-R60
Reassembling the governor lever assembly:
The governor lever assembly should be totally disassembled except for hollow setscrew (62) and nut M8
(63) (See Fig.A). <Note 1>
(Fig.-A)
Disassembling the Governor Lever Assembly: Disassembled hollow setscrew (62) and thin nut M8 (63)
should be reassembled to be flush with each other as shown
in Photo B and C.

back. (Photo D)
2. Install the outer governor wire (64). (Photo E)
(In case the end of inner governor wire should be bent, install inner and
outer wires together by taking measures of steps 3 and 4 below to get the
result as shown in Photo H.)
3. Insert inner part of governor wire (64) through throttle body (51)
(Photo F and G)
4. While pulling the end on inner wire which has come out of outer
part of governor wire, rotate it so that the gear teeth of slider is
visible. (Photo

5-1 OPERATION SYSTEM (MVH-120)
Disassembling:
1. Removing two bolts (26) allows to remove the
assembly of grip (25), lever bracket (33) and
throttle lever (35).
Disassembled operation system
Removing double nut (36, 37) causes throttle
lever (35) to come off the lever bracket (33).
To remove throttle lever from machine,
remove governor wire which has been screwed
down to engine.
2. Removing the bolt (13) allows to remove
travel lever (12) from hand pump (11).
3. Remove hydraulic hose (19) from the
connector (34) of vibrator shown in the
drawing of disassembled vibrator
4. With the two handle root mounting double nuts (5) removed, taking off the bolt (2) allows to remove
the handle (1) from the base.
! Note:After removing hydraulic hose, apply blind plug to prevent any dust from entering.
Removing hose clamp (20), its mounting bolt (21), hand pump locking nut (18) and two
stud bolts (pump) (16) allows to remove the hand pump (11) from handle (1).
Reassembly:
Reassembly should be conducted with the disassembling procedure reversed while observing below:
1. For installing the handle assembly (1) to the base, first lightly tighten the nut and bolt which have
been tightening the guard hook side of the machine and adjust the resistance of handle movement by
means of double nut (5) before retightening.
2. Resistance of handle movement should be adjusted with double nut (36, 37).
3. Set rpm of the engine on the high speed end should be adjusted on the engine side by means of engine
setscrew.
※Disassembly and reassembly procedures for MVH-150 is identical to those of MVH-120.
