Minster IOI - Press Servicing Overview and Safety; Lockable Switches and Valves

Regulations require employers to establish and follow a
program of regular periodic power press inspection.
Additionally, records of the inspection and maintenance
work performed must be kept. This portion of the man-
ual is intended to describe servicing procedures appli-
cable to various components on the press. Suggested
inspection procedures and a press inspection check list
are included in this manual beginning on page I-4.
SAFETY PRECAUTIONS
It will be necessary to momentarily turn on electrical
power and pressurize the pneumatic and lubrication
system in order to complete some of the press inspec-
tion checks.
WARNING
MAKE CERTAIN THAT ALL PERSONS ARE CLEAR
OF ANY PINCH POINTS ASSOCIATED WITH THE
OPERATION OF THE PRESS AND/OR ITS AUXILIARY
EQUIPMENT BEFORE THE POWER IS TURNED ON.
As a precaution against accidental starting during any
press inspection, or while maintenance work is being
performed, it is suggested that WARNING tags be
attached to the press controls. The tags serve as a
warning to others that someone is working on the
press. Some sample WARNING TAGS are shown in
Figure 1E.
LOCKABLE SWITCHES & VALVES
During service procedures, it is sometimes necessary
to shut off pneumatic or electrical power to prevent acci-
dental operation of press components and possible
injury to service personnel. Regulations require that
certain valves and switches must be lockable to prevent
unauthorized release of hazardous energy until all ser-
vice procedures are completed and all personnel are
safely out of danger areas. It is the user’s responsi-
bility to make certain that lockout procedures meet
all applicable safety requirements.
For further information on lockout procedures, refer to
the section entitled “Lockout Procedures for Mechani-
cal Power Presses” in the “Minster Power Press Safety
Manual,” Manual No. 805 (furnished).
WARNING
FOLLOW THE LOCKOUT PROCEDURES AS
ESTABLISHED BY YOUR EMPLOYER.
