used for the purpose for which they were intended and applies to the original
buyer only. Except as set forth above or in any product-specific warranty docu-
mentation, we make no other warranties, express or implied, including but not
limited to warranties of merchantability of fitness for a particular use.
Returns of a product for warranty must be accompanied by a Return Merchan-
dise Authorization number (RMA#), obtained by by calling Customer Service
at 800-327-8287, and sent, freight paid by us, to Donovan, 3353 SE Gran Park

We will pay no storage fees for a warranty product return prior to pick by us
or the freight company. If a warranty product return is scheduled to be picked
up by us, we will pick up the product at our earliest convenience. If a product
returned is found, in our judgement, to be defective in material or workman-
ship, our obligation under this warranty is limited to the repair or replacement
of the product, which will be made by us. Repair or replacement will be at our

If the product returned is found, in our judgement, to be non-warrantable, the
owner will be contacted to authorize repair work, purchase of a replacement
product or return of the product, all of which will be at the owner’s expense.
Payment authorization must be received by us before any non-warrantable
product is repaired, replaced or returned. All expenses associated with deliver-
ing the repaired non-warrantable product, a replacement product or the non-
warrantable product from our factory to the owner will be paid by the owner.
In no event will we be liable for any damages of any kind to person, product or

There must be at least 12" clearance between components and
tilt frame. If existing exhaust system or hydraulic system compo-
nents are located between tilt frame and cab, adjust component
locations as needed to achieve 12" of clearance.
If existing components interfere with base assembly installation,
and if moving existing components is not practical, fabricate
brackets as needed to prevent interference.
STEP 1: Locate mounting angles on both sides of truck frame,
centering brackets between cab and tilt frame. Align angles on
frame, mark and drill 5/8" holes and fasten with 5/8" x 2" grade
8 cap screws, flat washers and lock nuts (supplied by customer)
or weld in place (see caution).

To prevent damage to and ensure proper operation
of Quick Flip™ IV system, center base assembly be-
tween cab and hoist with at least 12" of clearance.

Spring Pivot Installation - Single Axle
STEP 1: Determine spring pivot mount locations on truck frame
rail. On driver side of truck, measure distance from back of base
assembly to back of longest container. Divide measurement in
half and mark location on truck frame. Repeat on passenger side.
NOTE: To obtain accurate measurements, load longest
container before measuring.
STEP 2A: Use mounting plates, elbows and tubes to fabricate
spring pivot supports for spring assemblies, modifying components
as needed (see next page for necessary dimensions).

Spring Pivot Installation - Tandem Axle
STEP 2A: Use mounting plates, elbows and tubes to fabricate
spring pivot supports for spring assemblies, modifying compo-
nents as needed (see next page for necessary dimensions).
STEP 1: Determine location for spring assemblies. To locate cen-
ter of spring assemblies to support arms to cover up to a 40-yard
container, measure 147" from back of base assembly. To ensure
tarp does not extend past rear of container, load truck’s largest
container onto truck and center spring assemblies between base
assembly and rear of container.
NOTE: Fenders on most trucks are not strong enough to
support spring assemblies. Fabricate spring pivot supports
to support weight and torsion of spring assemblies. Supports
must be square and level for system to operate correctly.
IMPORTANT: Locate spring assemblies as low on truck frame
as possible to allow clearance between roll-off container and
spring assemblies. Top of spring assemblies must be less
than 5" above rollers used to support container. If needed,
pull container onto truck and check for clearance.

STEP 2: Position pivot mount plate at marked location. Using holes
in plate as guide, mark hole locations on frame rail and drill 5/8"
holes. Fasten with grade 5 or better 5/8" bolts, washers and nuts
(not included). Repeat to install pivot mount plate in same location
on passenger side frame rail.
STEP 1: Determine spring pivot mount locations on trailer frame.
On driver side of trailer, measure distance from back of base as-
sembly to back of longest container. Divide measurement in half
and mark location on trailer frame. Repeat on passenger side.
NOTE: To obtain accurate measurements, load longest
container before measuring.
NOTE: Do not weld directly to trailer frame as this can weaken
frame and potentially void warranty. Components may be
welded to plates/structure already existing on trailer frame.
STEP 3: To determine spring pivot tube lengths, first measure
distance between outside faces of pivot mount plates (frame
width plus thickness of two plates). Subtract measurement from
overall width of 99-1/2" and divide remainder in half. Cut spring
pivot tubes to this length.

on spring. Slide spring pivot connector onto shaft so connector
is close to horizontal.

Pre-Load Springs
STEP 1: With return arms resting
on ground, slide pivot connector
off spring shaft.
Recommended pre-loads:
Single axle kits - No pre-load needed in most applications.
Tandem/multi-axle kits - One flat (1/6 turn) of pre-load can be
added but do not exceed that amount or spring may be dam-
aged. Tandem/multi-axle kits require less pre-load because
spring loads up more quickly.
Trailers - Start by turning three flats (1/2 turn) of pre-load and
increase as needed.
STEP 2: To pre-load spring, turn spring shaft (counter-clockwise
for driver side and clockwise for passenger side) until you feel
shaft engage rear hook on spring. Use 7/8" wrench or pipe wrench
to continue turning shaft in same direction until next flat on hex
shaft lines up with hex flats in pivot connector, then slide pivot
connector onto spring shaft.
STEP 3:
Pre-load spring one flat (1/6 turn) at a time on hex shaft
until desired pre-load is reached. Remove pivot connector after
each 1/6 turn, rotate connector to next flat and replace. When
desired pre-load is reached, secure pivot connectors to spring
shafts with set screws.

STEP 2: Remove reservoir shipping plug (red with square top)
from top of plastic reservoir. Fill reservoir with Dexron automatic
transmission fluid until it is just under the fill hole. Install black
breather cap into fill hole to replace shipping plug. Red shipping
plug can be thrown away or threaded into retainer at bottom of
reservoir.
STEP 3: Make connections at battery as shown. Ensure 4-ga.
cable/wire with red stripe is connected to pump solenoid and
is routed to manual reset breaker and positive post of battery.
Connect 4-ga. negative wire from stud on side of hydraulic pump
to negative battery post.
STEP 1: Remove pump enclosure cover and front panel to ac-
cess pump assembly.
CAUTION
Replace shipping plug with breather cap on
hydraulic pump or pump will be damaged.
!
NOTE: It is recommended to disconnect pump positive cable
from battery until pump has been filled with fluid.
CAUTION
Running the pump unit dry will damage the
pump.
!
CAUTION
Do not pull dual-strand wires apart. To sepa-
rate, carefully cut through insulation between
wires with knife. Pulling wires apart could
damage wire insulation and expose wire.
This could result in equipment damage and/
or personal injury.
!
STEP 4: Operate pump with toggle switches to raise tower. Watch
fluid level in reservoir while operating to make sure it does not
empty and introduce air into the system. If fluid level gets within
1-1/2" of the reservoir bottom, add a few more ounces of fluid.
After raising tower to maximum height, lower it back down again.
Raise and lower 2 to 3 more times to help remove air from the
system, then check fluid level with tower lowered all the way down.
Fill reservoir until fluid is about 1/2" under fill hole and reinstall
breather cap. Before reinstalling the enclosure front panel and
cover, test operation of tower, tarp motor and work lights with
both the toggle switches and with the wireless remote. See pg
16. for operating instructions.
