WELCOME TO THE WORLD OF RIKEN HYDRAULIC POWER EQUIPMENT!!
This operation manual explains operation procedures, warnings and cautions, and trouble shootings for
RIKEN manual-operated Hydraulic Pump Model
P-1B/P-1D
and its peripherals.
Before operation, requested to read this manual carefully, and understand the contents
thoroughly.
This manual should be in a safe place but accessible for reference during operation.
Cautions Regarding Safety
To use this pump safely, correct operations and periodical checking shall be requested.
Do not operate this pump before you read and understand safety instructions thoroughly shown in this
manual.
And follow
, this mark is used to prevent from causing property losses or damages,
also follow
, this mark is used to prevent from causing personal injury.
Ensure to follow above important warnings for safety. Switch the power off if abnormal condition
happens, and contact the sales agent.
(1)
Do not use in areas where severe damage may occur should hydraulic oil leak or escape.
Specifically, do not use near flammable materials due to the risk of injury and fire.
(2)
DO NOT MODIFY THIS PUMP.
Do not modify this pump. If any modification is required,
consult RIKEN or authorized agents of RIKEN before modification. RIKEN will assume no
responsibility for modifications performed without permission.
(3)
If operating this pump with air valve closed when returning the working oil to the tank, the
internal pressure in the tank could rise more than capacity. Ensure that air valve opened to
prevent damage to occur to the tank or personal injury.
(4)
When returning the oil to the tank, do not exceed the tank capacity. The internal pressure in
the tank could rise more than capacity causing damage to occur to the tank or personal injury.
(5)
The maximum output pressure of these pumps is
70 MPa
. For safety, each pump is factory
fitted with a high pressure safety valve adjusted to
73 MPa
. Do not allow the safety valve to be
increased a level higher than
73 MPa
.
(6)
When using hydraulic equipments which working pressure is less than
70 MPa
with this pump,
either lower the setting of the high pressure safety valve and adjust the pressure switch to
match the working pressure of the equipments. Be warned failure to lower settings could
result in the equipment damage.
(7)
Releasing the pressure suddenly from the jacking up cylinder or wire strand occurs to dropping
or bouncing of the loads, and it happens to personal injury. Consult RIKEN or RIKEN
’s
authorized agents regarding a suitable valve to prevent that.
(8)
Ensure to use the cylinders not exceeding the rated pressure capacity. If the pressure
exceeds the rated capacity, the cylinders and nylon hoses could damage, and occurs to
personal injury.
(9)
The allowable tilt on the cylinder piston should be less than
2.5%
. If applying more than
2.5%
,
the piston might be bent or the cylinder tube could be damaged.
(10)
Do place hands or other body parts near areas where hydraulic oil is being dispersed as high
pressure oil may penetrate the skin and cause serious injury. Do not touch the high pressure
hose pressured and around that.
