Operator Safety Instructions

To operate jacks safely requires dexterity, mechanical skills and sound safety habits.
Although Sumner jacks are manufactured for safe, dependable operation, it is impossible to anticipate those combinations of circumstances which could result in an accident. The following instructions are recommended for safe operation of this unit:

1. Read and understand the instructions for safe operation. Before working with a Sumner jack,  understand the correct operation, applications andlimitations. Always contact Sumner when in doubt. Be particularly aware of specific hazards. Store this safety
   manual in a clean area and always at a readily available location. Additional copies are available for download from www.southwire.com.

2. Inspect the equipment. Prior to using Sumner jacks, check all parts to ensure that they are in proper operating condition. Inspect legs for bends, breaks or metal deformation.
   CAUTION In the event of any jack stand leg deformation, discontinue use immediately.
   IMPORTANT Make any necessary repairs before attempting to use the jack.

3. Wear proper clothing. Hard hat or welding helmet, safety shoes and welding gloves should be worn as a precaution while operating this equipment.

4. Keep work area clean. Always keep floor in work  area clear of clutter for unobstructed movement around the jack.

5. Operate from proper position. Keep balance and proper footing at all times.

6. Keep alert. Avoid horseplay around equipment and keep bystanders at a safe distance. Do not allow children to operate jacks and always keep them out of work areas.
   CAUTION Never allow anyone under jack stand with load.

7. Do not misuse unit. Perform only the functions for which the jacks are designed. Never attempt to operate the equipment at more than the recommended capacity.
   WARNING   Modifying the jack stand can result in injury or death.

8. Operate only on level surfaces. Use the jack only on smooth and level surfaces to avoid tipping and the possibility of operator injury. 9. Hold both jack head and jack leg or carrying handle when transporting. To prevent foot injury, always carry jack by both the head and the jack leg or carrying handle. 10. Use only Sumner parts. Mixing other manufactured jack stand parts on Sumner jacks can result in operator injury.

Proper Operation:

IMPORTANT Inspect jack prior to each use to ensure legs are free of bends, breaks or metal deformation and that spanner nut rotates freely.

1. Sumner offers two different jack heights (hi and lo), that allow welders to work at a comfortable height, depending upon the diamter of the pipe or load. Based on the size of the material to be welded, select the correct jack for the job (see page 8 on jack height).
   

   Correct Jack Height
   Operator work level is at comfortable position.| Incorrect Jack Height
   Work too low for operator can result in back injury.

IMPORTANT Always use same height jacks (hi or lo) per load. Do not mix jack makes or head styles.

2. Position jacks 5 feet (1.5 m) to 12 feet (3.5 m) apart, depending on length and weight of load. For an extra margin of safety it is recommended to have at least 4 jack stands spread evenly under any load.

3. Adjust spanner nut so that at least 2–3″ (50–75 mm) of adjustment screw is showing out of the I.D. barrel.

4. To position jack to desired height, loosen set screw and lift I.D. barrel. Lock washer will unlock when I.D. barrel is being raised and will grip automatically with the slightest load pressure.
   WARNING Raising or lowering I.D. barrel with load on jack can result in serious injury.

5. To lower jack head, lift both I.D. barrel and lock washer to loosen barrel. While holding lock washer lower I.D. barrel to desired height. Release lock washer to secure I.D. barrel.
   IMPORTANT _ To avoid pinching fingers, release lock washer first before releasing I.D. barrel.

6. All jack heads used in the same fit-up job should be at equal heights.

7. Always center the load on the jack head.

8. Level load by rotating spanner nut.

Transporting Jack Stand:

Vee head assembly can be locked in the jack for transportation. Position locator hole in ID tube so that it is in-line with set screw. Tighten set screw so that the head cannot come out of stand.
WARNING Set screw should only be used to hold jack head in place during transport and should not be used to hold a load. Release set screw before putting jacks under a load.Jack head assembly can slide out of the I.D. barrel if jack is carried incorrectly. To prevent foot injury, always carry jack by both the jack head and leg or carrying handle.

Adjusting Ball Transfer Heads:

Ball transfer assemblies slide over each vee of the Sumner Vee Head Jack. Make sure set screws are fully recessed. Note that the ball transfer locations are adjustable to accommodate both small 3/8″ (10 mm) diameter pipe or larger diameter pipe up to 12″ (300 mm). 

CAUTION To be sure that pipe stays on the ball  transfer head when rotating, tighten set screws.

Adjusting Roller Head and Rubber Wheels:

Remove wheel attaching bolt and nut and reposition for correct pipe size.

Using Jack Stand with Threading Machine:
When using the pipe stand behind threading machines, pipe stand vee should be positioned so that the pipe has level entry into the threader. A pipe stand should be positioned under the pipe every 8 feet.

Hold-E Pipe Clamp (PN 785000) (Stainless Steel PN 784999):
The Hold-E Pipe Clamp is for use with vee heads to secure pipe 3/4″ to 6″ in diameter. The Hold-E Pipe Clamp is highly recommended as a quick, easy safety precaution for the welder when fitting up layout work or short pipe lengths.

Hold-Down Device (PN 781050):
Sumner offers as an option to vee head users, a quick-action chain vise to secure pipe up to 12″ in diameter onto the jack stand. The Hold-Down Device is highly recommended as a safety precaution for the welder when fitting up flanges, fittings or short pipe lengths.For users of larger pipe, a Chain Extension Kit (PN 781056) is available in increments of 12″.
