NOTE:Your boat lift is a very heavy piece of equipment. Improper use could result in
serious injury or death. For the safety of people and property please review the safety
guidelines below for your new boat lift.
Passengers should stand clear of the lift and not
be aboard when the lift is in operation.
Do not play on or near the lift.
Leave your automatic bilge pump turned on the
automatic setting to prevent the accumulation of
rain water.
Service your lift regularly.
Do not service the unit with the boat on the lift.
Use a mooring line for additional security.
Only use Basta Marine approved oil in lift.
Special biodegradable non-toxic hydraulic fluid
Visually inspect all parts and assemblies for
defects and damage prior to assembling the
lift.
Do not install the lift alone.
Install the lift on firm and level ground.
Verify the lower frame of the lift is level
before each use.
Turn the power off during periods of non- use.
This hoist is a heavy piece of equipment please
use with care.
The lift should not be used for any other
purpose besides the lifting of boats & watercraft.

OIL INJECTED INTO THE SKIN FROM HIGH PRESSURE
LEAKS IN HYDRAULIC SYSTEMS CAN CAUSE SEVERE
INJURY. MOST DAMAGE OCCURS DURING THE FIRST
FEW HOURS. SEEK MEDICAL ATTENTION IMMEDIATELY.
SURGICAL REMOVAL OF OIL MAY BE NECESSARY.
USE ONLY BASTA BIODEGRADABLE HYDRAULIC FLUID

After the lift is assembled and installed, all fasteners should
be checked for proper tightness and reinspected
periodically.

5. Test the lift on dry ground using the Up/Down Switch
( # 9) and the Key Fob Transmitters. Inspect the
system for leaks.
1. The Hydraulic Pump will arrive fully assembled. Make
s u re all the connections are snug to prevent leaks or
loss of power to the unit.
2. Install two AGM Marine Grade Batteries as shown
a b ove. Confirm that the POWER switch on the Control
Panel (#8) is OFF. Connect solar panel to the
solar controller (see page 15).
Connect the Black Link Cable (#19) between the two negative
terminals of the batteries. Connect the Red Link Cable (#21)
between the two positive terminals of the batteries. Connect
the Red Battery Cables (#13) to the positive terminals and the
Black Battery Cables (#12) to the negative terminals of the
battery bank as shown.
NOTE: Ensure battery cables are correctly connected
and their terminals are very tight (otherwise there is
a risk of overheating).
4. Slide the Hydraulic Cylinder Hoses through the
a c cess holes in the side of the White Fiberglass Box
(#10) and attach them to their corresponding
Quick Couplers (#4, #5).
Ensure each Quick Coupler is
completely seated and tight with
no gap at the connection joint.
Connection must be tight to open internal
check valve and allow fluid to flow. USE PLIERS

FIRST USE AND ADJUSTMENTS
Follow this “first use section” during your first loading of a boat onto the boat lift.
These are required adjustments to make the lift work correctly.
1. Place the boat over the lift to the following specifications:
a. If your boat is an outboard, inboard/outboard, or V-drive, the transom should be 2 inches off of the ends of the bunk boards.
b. If your boat is a mid-engine or shaft-drive, the transom should be 12 to 24 inches off of the ends of the bunk boards.
Disembark and raise the boat. If more than two inches of settling occurs, STOP, carefully lower the lift to remove the
boat and re-level the lift. Continue repeating this step until the boatlift can be raised into the full Over - Center position
without settling.
tm
3. Remove the boat. Verify that the lift frame is level. Re-level the framework if necessary.
NOTE: If you purchase a new boat, be sure it is within the weight capacity limits of the lift. Also remember that
these adjustments will have to be done again to accommodate the new boat.
First test lift on dry ground for oil leaks, remote control function and correct operation.
2.
IMPORTANT: After installation, the legs MUST be adjusted so that the lift frame is level.
Lift must move into Over-Center position when fully raised.

MAINTENANCE
Occasionally wipe the solar panel with a clean, damp cloth to preserve its charging performance.
INSPECT THE LIFT PERIODICALLY
After the lift is assembled and installed, all fasteners should
be checked for proper tightness and reinspected
periodically.
!WARNING
one

NOTICE
USE ONLY BASTA BIODEGRADABLE HYDRAULIC FLUID
We recommend Chevron Clarity® AW ISO 32 or CITGO Aquamarine® 46 hydraulic oils.
DO NOT add fluid with
lift in RAISED position
!
Once a month:
Inspect the hoses, cylinders and fittings for leaks and wear.
Check the wire terminals for snugness and corrosion.
Check the hydraulic fluid level.
At least every 6 months:
Check the battery levels.
The battery electrolyte should be slightly
above the indicator ring in each cell. Carefully
add DISTILLED water if necessary
Do not over-fill.

page 20
A fully automatic battery charger or
trickle charger may be used.
Do NOT use a high power manual or boost charger
unless the battery is disconnected!
The remote control electronics may be damaged.
1.This lift uses two 12V Group 31 marine deep-cycle batteries. When looking
for a replacement, note that the figure for Reserve Capacity is the most
important feature. Heavier batteries usually have more reserve capacity.
2.The batteries should not be allowed to remain in a substantially discharged
state. It may result in permanent loss of capacity. Do not deeply discharge
batteries more often than absolutely necessary; it may reduce the life of the
batteries.
3.The following graph shows the approximate numbers of complete lift
cycles that may be expected during the day over the course of the seasons
while keeping the battery adequately charged. This data is only very
approximate and is influenced greatly by weather, temperature, solar panel
placement and cleanliness.
