5.4 Pump Leveling
Carrier Arms Parallel Solder Pump:
Tools Needed:
− 1/16” Allen wrench,
− 5/16” Cresent wrench,
− Bubble level
Steps:
• Mount the pump onto the solder pot and snug the mounting screws. DO NOT OVER TIGHTEN.
• Bring to bear the (4) leveling screws leaving the lock nuts loose.
Note:
WHEN ADJUSTING THE PUMP, THE TWO MOUNTING SCREWS NEED TO BE LOOSENED PRIOR TO
MAKING ADJUSTMENTS TO ANY OF THE LEVELING SCREWS. THEN, SNUG BACK DOWN TO READ
THE LEVEL. TWO LEVELING SCREWS NEED TO BE ADJUSTED IN ANY ONE ADJUSTMENT.
EXAMPLE – WHEN PARALLELING THE PUMP TO THE CARRIER ARMS, EITHER THE RIGHT TWO
SCREWS WILL BE ADJUSTED TOGETHER, OR THE LEFT TWO SCREWS TOGETHER FOR
EAST/WEST ADJUSTMENT. AND THE BOTTOM TWO SCREWS WILL BE ADJUSTED
TOGETHER OR THE TOP TWO SCREWS FOR NORTH/SOUTH ADJUSTMENT IT IS ALSO
VERY CRITICAL TO ADJUST BOTH SCREWS EXACTLY THE SAME AMOUNT.

• Locate the level in the carrier arm as if it were a PCB. Note the position of the bubble. Place the level
on the pump housing stack the same way. Note the difference between the two bubbles. Determine
which two leveling screws will need to be adjusted and by how much.
Note: THE PUMP HOUSING STACK MUST BE PARALLEL TO THE CARRIER ARMS. THEY DO
NOT NEED TO BE LEVEL. LEVELING THE MACHINE IS THE NEXT STEP
• Re-check the level of the pump and lock down the (4) lock nuts. DO NOT OVER TIGHTEN.
Machine Level:
• Next level the machine , place level on the solder pump and level the machine on a
workbench. Bring the bubble dead center in both x and y positions by using the machine
legs. Once level has been achieved, lock legs in place with jam nut.
