CONCEPT AND MAIN APPLICATIONS
BVR340/ BVR440
BVR350/ BVR450/ BVR850
Cordless Concrete Vibrators
(14.4V, 18V)
These five models have been developed as the first Cordless concrete
vibrators of the MAKSTAR series models.
Using Li-ion battery as power source, these new models are superior
to the current VR250D series models in work amount on a single
battery charge. Model BVR850 features 2400mm (8.0ft) extra-long
flexible shaft for smooth mixing of concrete in deep forms.
Model BVR340 and BVR440 are powered by 14.4V Li-ion battery,
and Model BVR350, BVR450 and BVR850 by 18V Li-ion battery.
These new products are available in the following variations.

REMOVING
ASSEMBLING
1) Remove Nut 36 by tapping with plastic hammer as illustrated in Fig. 2. Flexible hose is now unfastened from Bearing
box, and the junction point of Flexible wire and Spindle will be seen by moving Flexible hose.
2) See Fig. 3. Fix Spindle by putting Wrench 8 on the flat surfaces of Spindle. Grasp the crimped portion of the hose with
water pump pliers. Disconnect Flexible wire from Spindle by turning clockwise with water pump pliers.
Do the reverse of the removing steps.
Important: Be sure that every threaded portion is securely tightened.

DISASSEMBLING
ASSEMBLING
1) Remove Flex-shaft section from Motor section as described in [3] -1 on page 2.
2) Remove Bearing box from Housing by unscrewing four 4x20 Tapping screws.
3) Remove Cover complete as illustrated in Fig. 4.
4) Remove Housing R from Housing L by unscrewing nine 4x20 Tapping screws.
5) Remove Ball bearing 629LLB from Spindle with Bearing extractor (No.1R269) (Fig. 5).
6) Remove Supporter from DC Motor by unscrewing two M4x12 Pan head screws.
1) Install Supporter on DC Motor by fastening two M4x12 Pan head screws.
2) Set the assembly of DC Motor and Supporter in jigs as illustrated in Fig. 6. Press down Ball bearing 629LLB with
arbor press all the way until it stops against the stopper on Spindle.
Important: Be sure to do the above steps. Do not press down Spindle into Ball bearing 629LLB or Spindle press-fitted
on Motor shaft will be moved out of place (Fig. 7).

[3] -3. Flex-shaft Section
DISASSEMBLING
1) Remove Flex-shaft section from Motor section as described in [3] -1 on page 2.
2) Fix adjustable wrench in vise. Fix Flex-shaft section with adjustable wrench by fitting the flat surfaces of Flexible hose
in adjustable wrench. Separate Pipe 25 from Flexible hose by turning in the direction of the arrow using a pipe wrench
with length of 450mm or longer. (Fig. 8)
3) Fix Pipe 25 in vise by fitting the flat surfaces of Cap in the lips of vise. Remove Pipe 25 by turning in the direction of
the arrow using the same pipe wrench as used for removal of Flexible hose. (Fig. 9)
Flex-shaft section can now be disassembled as illustrated in Fig. 10.
4) Fix Unbalancer section in vise. Put Wrench 9 on the flat surfaces of Joint. Remove Joint by turning in the direction of
the arrow with the wrench. (Fig. 11)
5) Remove Retaining ring S-6 with Retaining ring S and R pliers (No.1R291). Remove Rubber ring and Felt ring. (Fig. 12)
6) Remove two 626LLB Ball bearings and two 626 Ball bearings from Unbalancer using Bearing extractor (No.1R269).

ASSEMBLING
1) Saturate Felt ring with Lubricating oil VG46. (Refer to [2] LUBRICATION.) Assemble Felt ring to Rubber ring.
Note: Replace the rings with new ones if they are damaged.
2) Assemble Unbalancer section. (Refer to Figs. 13, 12, 11.)
3) Apply Threebond 1303 to the whole threaded portion of Cap. Fasten Cap securely to Pipe 25. (Refer to Fig. 9.)
Important: Be careful not to apply the bond to Cap other than the threaded portion.
4) Insert Unbalancer section into Pipe 25 all the way until it stops (Fig. 14). Adjust the position of Rubber ring so that
the end surface of Rubber ring is flush with that of the opening of Pipe 25 (Fig. 15).
5) Fasten Flexible hose securely to Pipe 25 while inserting Rubber ring into place. (Refer to Fig. 8.)
Important: Be careful not to tilt Rubber ring.
