DAILY (cont.)
•
Lightly resurface both lower jaw surfaces together with a fine grit surfacing stone to remove any high spots and embedded
debris.
•
Lightly lubricate the clamp block slides with oil before reinstalling the clamp blocks. (Any oil 30 weight or heavier)
WEEKLY
•
Perform the DAILY maintenance procedures
•
Remove the lower jaws and blade guide mount rails as described later in this section.
•
Clean and inspect the jaws and carriages for wear and damage.
•
Using a fine grit surfacing stone, lightly resurface the bottom (beveled side) of the lower jaws to remove any high spots or
debris.
•
Using a fine grit surfacing stone, lightly resurface the lower jaw mount surfaces on the carriages (together, not separately),
the guide mount surfaces on the front of the carriages (together, not separately), and guide rail mount surfaces on the sides of
the carriages.
•
Clean your entire welder. This will make it easier to see potential problems and help keep dirt from building up in critical
areas of the machine.
•
Inspect the air and hydraulic system for leaks or worn hoses and repair or replace, if necessary.
DANGER: Make sure all hydraulic pressure has been evacuated from the system before beginning any maintenance to the
hydraulic system
. To relieve pressure, disconnect air from the welder. Turn the welder ON and press either of the
clamping foot pedals. Turn the welder OFF and do not re-connect air to the welder until all maintenance has been
completed.
•
Check the oil level in the hydraulic pump reservoir and add oil, if necessary. A drop in the oil level would indicate a leak in
the system, and should be corrected as soon as possible. (Hydraulic Oil Type AW68)
•
Check the oil level in the air lubricator and add oil as needed. It is normal for the air lubricator to loose oil, and should need
filling once every month or so. If it is not loosing oil, it may be set too low and needs to be opened further to prevent damage
to the hydraulic pump. (Any 10 weight oil such as Air Tool Oil)
•
Check the air filter/accumulator for water accumulation and excessive dirt. There is an auto-drain located on the bottom of
the filter bowl to drain water out. If there is a lot of dirt in the bowl, it will need to be removed and cleaned.
•
Remove the left and right front covers from the welder. Check the oil level in the oil cup, located under the cam on the left
side of the welder, and fill if necessary. (Any oil 30 weight or heavier)
•
Blow out the timing cut-off switch slide with compressed air and lubricate with a lightweight oil. (i.e. 3-IN-1 Oil)
•
Clean and lubricate the main shafts and bearings WITHOUT REMOVING THEM . (Any lightweight oil, i.e. 3-IN-1 Oil)
•
Lubricate the drive rod at all friction points, including the threaded portion of the rod where it screws into the drive bushing.
(Any oil 30 weight or heavier)
•
Lubricate the lever pivot pin. (Any oil 30 weight or lighter)
•
Check the timing calibration (see GENERAL SETUP).
•
Check the jaw gap indicator calibration (see GENERAL SETUP).
•
Check the water-cooling pump for proper operation. Check water lines and fittings for leaks. Fill the water tank as needed.
