Installation; Operation - Makita VR001G Instruction Manual

ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
Installing and removing flexible
shaft
Optional accessory

Installation

1. Pull the flexible core shaft reasonably straight out
of the outer casing.
► Fig.16: 1. Flexible core shaft 2. Outer casing
2. Hold the drive shaft in the tool still using the
wrench provided. Then hand thread the end fitting of the
flexible core shaft onto the solid drive shaft in the tool.

shaft
3. Fasten the end fitting of the flexible core shaft up
tightly using a pair of pliers.
► Fig.18
4.
Hand thread the coupling of the outer casing onto
the male thread of the tool.
► Fig.19: 1. Coupling 2. Outer casing 3. Male thread
If the coupling does not reach or fit securely onto the
male thread of the tool, especially when installing a long
flexible shaft, pull the outer casing further towards the
tool while hand-turning the flexible core shaft so the
shaft top well fits into the shaft slot in the vibration head
and becomes fully engaged.

5. Knock each of the three corners of triangular
coupling with a hammer a few times in random order to
secure assembly.

Uninstallation
Follow the installation steps in reverse order.
Installing shoulder strap
Optional accessory
WARNING:
Always remove the shoulder strap
from the tool while wearing portable power packs.
Wearing multiple harnesses and straps may impair
the chances to take the equipment off quickly in a
case of emergency and result in personal injury.
WARNING:
Do not use the parts for attaching
the shoulder strap for other purposes, such as
the fall prevention at high location. If the parts
for attaching the shoulder strap are used for other
purposes, excessive load may break them and cause
serious injury to the operator and person around/
underneath the operator.
CAUTION:
Be sure to attach the hooks of the
shoulder strap to the tool securely. If the hooks are
attached incompletely, they may come off and cause
injury.
CAUTION:
Be sure to use the shoulder strap
dedicated to this tool. Using other shoulder strap
may cause an injury.
Hang the hooks of the shoulder strap over the hanging
holes on top of the tool.

OPERATION

CAUTION:
Put the shoulder strap on the
shoulder, and hold the tool firmly with both
hands.
NOTICE:
At the very beginning of operation, the
flexible shaft tends to vibrate at a higher ampli-
tude. The tool will restore the normal amplitude
after you squeeze and release the switch trigger a
few times repeatedly.
Make sure to throw in and keep the vibration head
stand straight during operation. Use the tool within the
effective vibration ranges at equidistant intervals. The
effective air bubble removal range is approximately ten
times the diameter of vibration head.
► Fig.23
► Fig.24
NOTICE:
Do not use the tool to move concrete
in the formwork. The mortar will just move away
and the coarse aggregate will remain, causing
segregation.
► Fig.25
Effective leveling and removal of air
bubbles
Removal of the air bubbles is complete after you have
worked the tool throughout each effective range, the
concrete stops shrinking, and the mortar has risen
evenly to the surface, giving off a light appearance.
Gently remove the operating tool not to leave holes.
When using the tool on slope, always operate it from
the bottom at the beginning. If you operate the tool from
the top, the mortar will separate and eventually slide to
the bottom.
► Fig.26
► Fig.27
NOTE: Vibrating too long in a single place causes
concrete segregation.
NOTE: When the coarse aggregate segregates when
placing concrete, shovel out the coarse aggregate
and put it where there is plenty of mortar. Then use
the tool on it. Don't leave coarse aggregate in the
segregated condition.
