Frequently Asked Questions / Installation

The MaxJax™ manual provides comprehensive support when installing and using the MaxJax™ Lifting System. We provide these frequently asked questions to help clarify some areas of confusion and offer business procedures and processes when ordering a MaxJax™ Lift.

Please select a FAQ category below to find the answers to questions you're looking for. If you can't find a question that relates to you, or would like us to elaborate on an answer, please contact us.

Is installation included in the price of a MaxJax™ lift?

Installation is not included. Although most users install the anchors themselves, we are able to source a local contractor if you are not comfortable in doing so. If you would like to have a local independent contractor install your lift anchors, Dannmar can help arrange by recommending a certified installer in your area.

How much would it cost for a professional installer to install my lift anchors?

Professional installers would charge depending on several factors. It is best to call Dannmar to assist you in finding the right installer, for the right price.

Do I need any special tools to install my lift?

The only specialty tools required are a rotary hammer drill, a 5/8" concrete for a pilot hole, and a 7/8" drill-bit for the drop-in anchors. If you don't have a rotary hammer drill you can usually rent one. Other tools required will be standard wrenches.

Does my lift come with anchor bolts and/or the hardware to mount it to the floor?

MaxJax™ lifts ship with all necessary anchors and bolts required for mounting the unit to your floor.

What size are the anchor bolts and what size drill bit do I need?

The drop-in anchors for all MaxJax™ lifts are 7/8" diameter x 4" long. A rotary hammer drill, a 5/8" concrete for a pilot hole, and a 7/8" concrete bit for the drop-anchors are required for installation.

Is electrical hard wiring included in installation?

Electrical work is not necessary. The standard power unit features a dual voltage 115/208-230-volt AC, single phase motor with an industrial-grade power cord and standard household plug.

What type of power outlet/source is needed to operate my lift?

Our standard power unit will require a 20 amp (14.5-14.8 amp draw)110V Outlet to operate at standard 110V Power and a 15 amp ( 7.3-7.4 amp draw) 220V circuit to operate it at optional 208-230Volt.

What is the benefit of using 220V?

Lifting time will decrease slightly (.90 gallons per minute on 110V and 1.09 gpm on 220V ) and your amp draw will be ½ of the 110V circuit.

Does the hydraulic fluid come with the lift?

Due to current DOT and insurance laws regarding the transport of hydraulic oils ( DOT / Section 1 -- Hazardous Ingredients, DOT / Section 2 -- Fire and Explosion Hazards and DOT / Section 3 -- Health Hazards ) hydraulic fluid is to be supplied by the end-user only and will be required for operation. MaxJax™ lifts are designed to operate using standard 10-weight, non-foaming, non-detergent hydraulic oil or Dexron-III ATF fluid. This is available in virtually any automotive store.

How much hydraulic fluid is required for my new MaxJax™ lift?

7-quarts of standard 10-weight, non-foaming, non-detergent hydraulic oil or Dexron-III ATF fluid.

Do I need a special floor or foundation to support my lift?

Most residential or commercial foundations are strong enough to support a MaxJax™ lift. The minimum requirements are 2500-3000 PSI 4" thick concrete. Be sure to check your floor on the possibility of it being a post tension slab. In this case contact the building architect before drilling. Visually inspect the site where the lift is to be installed and verify the concrete is in good condition. If your concrete has cracks or other defects, please consult with a certified contractor before proceeding to install the MaxJax™ lift.

Should I pre-mount the drop-in anchors in fresh concrete?

Although we don't recommend it, if you are careful to locate the anchors at precisely the correct spacing and depth, then this is an optional method of install. Mounting hole loctions can vary. Always consult concrete professional when installing new concrete and/or pre-mounting the drop-in anchors.

My driveway has a slight decline, do the posts have to be perfectly plum? Can I make a shim to compensate?

The columns should be parallel to each other assuring the pads remain equal distance apart as the lift rises.

In the event the columns were tilting outwards, the pads on the left column would be moving away from the pads on the right column as the lift ascended.

In the event the columns were tilting inwards, the pads on the left column would encroach the pads on the right column as the lift ascended.

This could cause a shifting of the pads under the vehicle that could possibly disrupt the vehicle balance. A slight unlevel front to back is acceptable as long as it does not exceed a 1-1/2" slope in a 20' distance and the pads remain relatively level with each other and the posts remain parallel.

A set of "C" shims are included with each MaxJax purchase.

What is the ceiling height required for the MaxJax?

The required ceiling height would vary depending on which vehicle is being lifted. The maximum lifting height of the MaxJax with the pad only is 45" / 1143 mm. Take that measurement and add it to the distance from the bottom of the lifting points on your vehicle, to the very top of your vehicle. The total will give you the minimum ceiling height required for your situation.
