Features and Benefits

The Daytona [DJ300MP] 3 Ton Professional
Super Duty Jack was engineered for automotive professionals. The
Model [DJ300MP] features Advanced
Rapid Pump® technology for fast lift times and exceptionally long life.
Long-Life Advanced Rapid Pump® Hydraulics
The hydraulic power unit is designed to provide over 5000 lift cycles with minimal wear.
An Integrated Magnetic Filtration (IMF)
System prevents contaminants from damaging pump pistons and other high pressure components.
Precision-engineered high performance seals along with a sealed non-vented reservoir ensure longer fluid life with no leaks.
Rapid Pump technology delivers twice the lift force with each stroke to lift heavy loads in half the time of conventional hydraulic systems.
The pistons are continuously force-loaded to keep the pump handle in ready position during use. Load limiters with a bypass valve protect the pump if an overweight load is attempted.
Low-Profile/High Lift Saddle
The Low Profile design gives you a minimum height of just 3.75″ for working with low-clearance vehicles. The extended lift arm provides High Lift for a maximum height of 23.125″ for plenty of working space when properly supported. The big 5″ x 5″ saddle supports lift points solidly without danger of slipping. The saddle can be removed to install lifting accessories (sold separately.)
Super Duty Strength and Durability
The Daytona Super Duty Professional Jack chassis is constructed from all- welded steel plate with I-beam reinforcement for extraordinary strength and reliability.
Contoured steel wheels and casters roll smoothly with less surface area contact for exceptional mobility. Fully lubricated with dual bearings and easy access grease fittings.
Effortless Operation
Get easy leverage and positioning with the extra long foam-protected lift handle. All moving components are factory lubed for smooth action with easily serviceable grease fittings in the lift mechanism. A locking spring mechanism keeps the handle in place during use.
The Rapid Pump® system gives you easy-twist universal joint hydraulic release for precise, controlled lowering.

Set Up

** Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.
Removing Shipping Clip
CAUTION!** The Handle socket may be held down by a clip under tension. Wear ANSIapproved safety goggles before freeing Handle socket. Remove clip carefully.
A wire clip holds the Handle Socket in position during shipment. This helps prevents shipping damage. To remove it:

1. Press down on the Handle Socket to relieve tension on the wire clip.
2. Disconnect the wire clip legs from the bar.
3. Slowly raise the Handle Socket until tension is released.
4. Remove the wire clip.

Attaching the Handle

1. Slide the Upper Handle into the Lower Handle. Line the Button on the Lower Handle up with the hole in the Upper Handle until it clicks into place.
2. Pull on the Handle Release and insert the grooved end of the Handle into the Handle Socket.
3. Let go of the Handle Release. Gently pull up on the Handle to make sure that it is secure.

Bleeding Trapped Air

1. With the Jack fully lowered, remove both Screws on the end of the Cover Plate that is closer to the Saddle. Swing the Cover Plate open. See Figure A.
2. Remove the Fill Plug on top of the Cylinder. Check that the oil level inside the Cylinder is at the top of the Piston. See Figure B.
3. Insert the Handle into the Handle Socket to operate the Release Valve.
4. Turn the Handle counterclockwise to open the valve.
5. Pump the Handle up and down quickly 10-15 times to force air from the system.
6. Replace the Fill Plug, close the Cover Plate, and reinstall the Screws.

Adding Oil
NOTICE: To prevent damage and premature wear, use only 22 viscosity, non- detergent hydraulic jack oil.

1. With the Jack fully lowered, remove both Screws on the end of the Cover Plate that is closer to the Saddle. Swing the Cover Plate open.
2. Remove the Fill Plug on top of the Cylinder.
3. Add non-detergent 22 weight hydraulic jack oil into the Fill Plug hole slowly until the oil level just reaches the top of the Piston inside the Cylinder.

Operation

** Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.
Lifting
WARNING WARNING
**Park vehicle on a flat, level, solid, surface safely away from oncoming traffic. Turn off the vehicle’s engine. Place the vehicle’s transmission in “PARK” (if automatic) or in its lowest gear (if manual). Set the vehicle’s emergency brake. Then, chock the wheels that are not being lifted.

1. Turn the Handle counterclockwise to lower the Jack. Once the Jack is fully lowered, turn the Handle firmly clockwise to close it.

2. Carefully position the Saddle of the Jack under the vehicle manufacturer’s recommended lifting point. (See vehicle manufacturer’s owner’s manual for location of frame lifting point.)

3. Pump the Handle until the top of the Jack’s Saddle has nearly reached the vehicle lifting point. Position the Saddle directly under the vehicle’s lifting point.

4. To lift the vehicle, pump the Handle of the Jack. Use smooth, full strokes.

5. Once the vehicle is raised, slide a jack stand of appropriate capacity (not included) under a proper lifting point referred to in the vehicle owner’s manual. Always use two jack stands, position them at the same point on each side of the vehicle.
   WARNING! The rated capacity of jack stands is per pair, not the individual capacities combined unless specifically noted on the product by the jack  stand manufacturer. Do not exceed rated jack stand capacity. Ensure that the vehicle support points
   are fully seated in the saddle of both jack stands. Use a matched pair of jack stands per vehicle to support one end only. Failure to do so may result in the load suddenly falling, which may cause personal serious injury and/or property damage.

6. Center the vehicle’s lifting point(s) on the saddle of the jack stand(s). Set the jack stand(s) to the same height according to the manufacturer’s instructions, making sure that they lock securely into position.

7. Slowly turn the Handle counterclockwise to lower the vehicle onto the saddle(s) of the jack stand(s). Then, turn the Handle firmly clockwise to close it.

Lowering

1. Carefully remove all tools, parts, etc. from under the vehicle.
2. Position the Saddle under the lifting point. Turn the Handle firmly clockwise and raise load high enough to clear the jack stands, then carefully remove jack stands.
3. Slowly turn the Handle counterclockwise (never more than 1/2 full turn) to lower the vehicle onto the ground.
4. Lower the Jack completely. Then, store in a safe, dry location out of reach of children.

   ALSO, BEFORE EACH USE, thoroughly test the Jack for proper operation prior to actual use.
   If the Jack’s motion seems spongy or the Saddle does not lift completely, follow Bleeding instructions on page 6.

2. AFTER USE, wipe dry with a clean cloth. Then, store the Jack in a safe, dry location out of reach of children and other non-authorized people.
   NOTICE: Storing the Jack in a humid area or exposing it to corrosive vapor voids the warranty.

3. Weekly – Jack Lubrication:
   a. Lubricate according to the below steps using only general purpose lithium grease.
   b. Inject grease into each of the 5 grease fittings.
   c. Lubricate the linkages and pivot points lightly.
   Note: Improper or inadequate lubrication voids the warranty.

4. Change the hydraulic oil at least  once every three years:
   a. With the Jack fully lowered, remove both Screws on the end of the Cover Plate that is closer to the Saddle. Swing the Cover Plate open.
   b. Remove the Fill Plug on the top of the Cylinder.
   c. Tip the Jack to allow the old hydraulic oil to drain out of the Housing completely, and dispose of the old hydraulic oil in accordance with local regulations.
   d. Turn the Jack upright. Add non-detergent 22 weight hydraulic jack oil into the Fill Plug hole slowly until the oil level just reaches the top of the Piston inside the Cylinder.
   e. Replace the Fill Plug, close the Cover Plate, and reinstall the Screws.
   f. Follow instructions for Bleeding Trapped Air on page 6.
