DANGER
• Do not exceed the maximum weight capacity specified for the lift. Maximum weight
capacity can be found on the cover of this manual and on the H frame of the lift.
Improper use or failure to follow this instruction can cause property damage,
serious injury, or death.
• Never use for lifting humans or animals. Improper use or failure to follow this
instruction can cause property damage, serious injury, or death. The lift should only
be used for lifting boats & watercraft.
• Always avoid being under, and maintain adequate clearance from, the lift. Failure to
follow this instruction can cause serious injury or death.
• Always use AGM batteries and follow battery manufacturer’s warnings and instructions.
Improper use, or use of other batteries, have the potential to produce flammable hydrogen
gas which can result in serious injury or death.
• Visually inspect all parts and assemblies for damage or defects prior to assembling lift.
• Install the lift on firm and level ground.
• Verify the lower frame of the lift is level before each use.
• Do not play on or near the lift.
• Do not service the unit with the watercraft on the lift.
• High pressure hydraulics can penetrate skin. Oil injected into the skin from
high pressure systems can cause severe injury. In the case of injury, seek
medical attention immediately.
WARNING
• Do not install the lift alone.
• The lift should only be used for lifting boats & watercraft.
• Passengers should stand clear of the lift when the lift is in operation.

Step 1: Slide the Hydraulic Hose Assembly through the
access hole in the side of the fiberglass enclosure and
attach the ends to their corresponding Quick Couplers.
Ensure each Quick Coupler is fully seated, tight and
with no gap at the connection joint.
Step 2: Remove shipping plug in hydraulic reservoir and
replace with breather plug before first use.
Step 3: Install Battery as shown. Connect the Red Battery
Cable to the positive terminal (+) and the Black
Battery Cable to the negative terminal (-).
Step 4: Before moving into the water, test the lift on dry
ground using the Up/Down Switch and the Key Fob
Transmitters. Inspect the system for leaks.

Test lift on dry ground for leaks, remote control function and correct operation before moving into
water. Tighten all hardware.
Lower the lift completely, then raise it slightly. Disconnect the Hydraulic Hose Quick Couplers in the
Power Unit box to separate it from the lift.
Move the lift to nal destination. Use this diagram to help place the lift. Lift placement should be so
that the top of the aft end of the bunks are one foot above the high-water mark when the lift is in the
full up position, and one foot below the low water mark, when the lift is in the down position.

IMPORTANT: The leveling process must be completed to ensure stability of the lift frame
and Over-Center safety lock.
Level the lift following these instructions while referencing image below:
Step 1: Use a tape measure (reference image on right) to determine that the lower
frame is level.
Step 2: If the lower frame needs to be raised start with the lowest corner first then
work your way around the lift in a circle, corner to corner. Adjust the lift legs as needed.
Step 3: To make adjustments, first make sure the lift is properly supported.
Then, loosen the anti-sway bolts, remove the P-pin and raise or lower
the lift crossmember on the leg. Level the lift one corner at a time,
while making sure not to have more than 5” of difference in height
between the corners to prevent binding.

Leveling requires a second person to support the crossmember while making adjustments.
If the lift is too heavy for two people, a ratchet strap or winch system will be required to
raise/lower the frame corners.

Re-connect the Hydraulic Hose Quick Couplers inside the Power Unit box.
Fully raise lift and finish adjusting the legs so that the base frame is level side-to-side and
forward-to-aft. After the lift is assembled and installed, all fasteners should be checked for
proper tightness and reinspected periodically.
Load the boat onto the lift using the following
operational instructions:
1. Align the boat so it is centered between
the bunks side-to side.
2. Move the boat forward to position its center of
gravity near the bunks’ centers.
Perform the following adjustments to finalize
the lift installation:
1. 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 lift can be raised into the full
Over-Center™ position without settling.
2. Remove the boat. Verify that the lift
frame is level. Re-level the framework if necessary.
3. Check all bolts for proper tightness.
OPTIONAL
The lift legs can be cut off above the leg sockets after installation for a cleaner
look. First, make sure that the lift has fully settled and has been re-leveled.
NOTE: If you plan to add a canopy, relocate the lift into deeper water, or load a
heavier vessel in the future, you must keep the existing leg length.
Shown: examples of fore and
aft placement of the boat
on the boat lift, which varies
based on engine location.

IMPORTANT:
• If you purchase a new vessel, make sure does not exceed the weight capacity limits of the lift.
Maximum weight capacity can be found on the cover of this manual and on the H frame of the lift.
• Always turn power unit OFF when not in use.
• Keep inside of power unit box dry.
• To prevent unauthorized use lock box using padlock through the latch hasp.
• Securing your mooring line to the dock may provide additional security should the lift be lowered
inadvertently.
• Leaving your bilge pump on the automatic setting may prevent the accumulation of rainwater in
your vessel and overloading of the lift.
• Service your lift according to recommended Maintenance (page 19).
• Only use Basta Boatlifts approved fluid in lift. Contact Basta Boatlifts or authorized dealer for
approved biodegradable hydraulic fluid.
• When not in use, store the lift in the upright position to prevent it from being an unknown hazard
underwater.
• Store with the power off.
Step 1: Power on. Using the manual switch on the control panel, switch the On/Off switch to the
“On” position.
Step 2: Lower the Lift. Using the Key Fob, unlock the Fob by pressing and releasing the lock button.
Next, press the down button to lower the lift.
Step 3: Carefully guide the watercraft off the lift. Repeat in reverse order upon return.
For more questions or troubleshooting, consult your Authorized Dealer, the FAQs page on
Bastaboatlifts.com or give us a call at 425-641-8911.
OPERATIONAL INSTRUCTIONS

PAGE 20
FOB POWER-UP
After turning on the ON/OFF switch in the dock box, the fob
receiver requires a 5 second delay before the fob is enabled.
FOB OPERATION
Depress the unlock button (lower right), this will allow normal
operation of the fob. The lockout is re-enabled after 60
seconds without a button press. Lift operation using the fob
is limited to 120 seconds of continuous operation. If a longer
cycle is needed it is necessary to release button and then
re-depress.
FOB PROGRAMMING
1. Turn off the ON/OFF switch.
2. Wait 20 seconds.
3. Turn power back on, and within 5 seconds of
power on, press both the UP and DOWN buttons
on the fob simultaneously for 1 second then
release.
4. Repeat steps 1-3 for additional Fobs. Up
to four fobs may be enrolled. If a fifth fob
is enrolled, the first enrolled fob will fall off the list.
BATTERY REPLACEMENT
Fob uses CR2032, 3 volt battery, commonly found online or at
drug / hardware stores. Part numbers vary by manufacturer.
LOW BATTERY LOCKOUT
The remote control contains a low voltage lockout which
is intended to protect the lift’s battery from over-discharge.
When the battery drops below the low battery threshold
during operation, further use of the fob is not allowed. The
manual UP/DOWN switches will allow the lift to operate
when sufficient battery power is present. The lift should
be checked and charged prior to further operation.
TROUBLESHOOTING
If fob worked previously, but
does not currently, replace fob
battery or verify fob battery
has greater than 3v. If fob does
not work after replacement
of fob battery, load test lift
battery ensuring voltage does not drop below 11v while
in use. If you have questions, contact your local dealer or
Basta Boatlifts.
UNDERWATER LIGHTS
The underwater lights are activated whenever the
lift is operated. The lights stay on for 2 minutes
after the lift is operated. The lights may be
manually turned on or off by depressing the lower
left button on the remote fob. When manually enabled the
lights will automatically turn off after
4 minutes. This prevents accidental battery discharge.
