Preventative Maintenance
Schedule
The operating conditions of your particular system
determine how often maintenance is required. Establish
a preventive maintenance schedule by recording when
and what kind of maintenance is needed, and then
determine a regular schedule for checking your system.
Flushing the System
Flush the Pump:
• Before the first use
• When changing material or fluid part number or
brand
• Before fluid can dry or settle out in a dormant Pump
(check the shelf life or pot life of catalyzed fluids)
• Before storing the Pump.
Flush with a fluid that is compatible with the fluid you are
pumping and with the wetted parts in your system.
Check with your fluid manufacturer or supplier for
recommended flushing fluids and flushing frequency.
To flush the system, perform the following procedure:
1. Place a drum of compatible flush material under the
Follower Plate (D).
2. Run the Pumps to move the flush material through
the system for approximately 1 to 2 minutes or until
the solution is clean.
3. Remove the drum containing the flush material from
under the Follower Plate (D).
4. Return the system to previous operation settings.
Cleaning the System
To clean the system, perform the following procedure:
1. Turn the RAM POSITION Switch (AG) to RAISE,
then press the RAM UP Pushbutton to move the
ram to the fully raised position.
2. To lock the ram in the fully raised position, move the
RAM POSITION Switch to the HOLD/NEUTRAL
position and insert both safety hitch pins (806) into
the outer support bars (802) and install both pin lock
clips.
NOTE: Locks that use 1/4 in. shackles can be used in
place of the cotter pins (CP) provided with the safety
hitch pins (806).
3. Once both safety hitch pins (806) are secured, turn
off all air to the system by closing the Main Air
Shutoff Valve on the header (P) and follow your
facility’s pre-established lock-out/tag-out
procedures. See F
IG
. 16 on page 35.
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest
possible pressure.
NOTICE
Cleaning the system after using it can prevent material
contamination, which may cause the material to fail or
perform poorly. Do not load new material into a
contaminated system.
Clean the system to avoid untimely equipment
malfunctions and to ensure that system components
operate efficiently
